I've placed a simple bar chart into an SSRS report which is designed to display a series of Consultant Names (along the x axis), with a corresponding count of patients who are flagged as being in the category ">18 Weeks" (on the y axis), based on the following expression:
=SUM(IIF(Fields!RTTWaitGroup.Value=">18 Weeks",1,0))
The chart renders fine. However, a number of the Consultants listed in the chart have a zero count, and therefore are listed across the x axis but with no vertical bar displayed, as you'd expect.
I'd like to configure the chart so that it only displays those consultants that have a count of 1 or more patients.
I'm not overly familiar with the syntax, but I've tried using the following expression in both the Series Properties and Chart Properties 'Visibility' options, to try and suppress x axis categories that are zero, but it doesn't have any effect on the chart:
=iif(Fields!LastConsultant.Value ="",True,False)
Please can anyone advise on correct syntax and appropriate expression field to enter it?
Presumably your consultant names will be in the category group, if so right mouse click and select category group properties.Select Filters, in the expression enter count(fields!patients.value)... for example. Change type to integer , operator to greater than and the value to 0.
I want to be able to store a circle using a fixed point g and radius d, then get those values back when retrieving the information.
The only way I've found to use those arguments to create a geographic object is to use buffer which produces a polygon:
https://dev.mysql.com/doc/refman/5.6/en/spatial-operator-functions.html#function_buffer
SELECT ASTEXT( BUFFER ( POINT( 10, 10 ), 5 ) );

My problem with this is that I cannot retrieve the point and radius when selecting this row in the future, instead I get the polygon back.
Is there not a better way to store a circle for use with MySQL GeoSpatial Extensions?
Spatial databases are not great at storing curves; rather they tend to be approximated by lots of straight segments, so you're not actually retaining a circle. Support for curved geometries is improving but it's still not really there.
I would probably store the geometry as you have, as well as the radius as a floating point value.
Alternatively, if you only want to store the geometry, you can obtain the centre of the polygon ("circle") with the Centroid function, and then get the radius by converting the polygon to a line and determining the distance between the centroid and the line. There are other ways to determine this distance, too. the caveat is that because this is only an approximation of a circle, the distance between the centre of the circle and its edge is different when measured between the centre and one of the vertices, and when measured from the centre and an edge between two vertices. So if you do not store the radius independently of the geometry, ideally you should measure distance between a vertex and the centre, which will be equal to the original radius (buffer distance). Practically the difference will be rather small so long as your "circle" has dense vertices.
I have an SSRS Line chart which plots supply points with square feet on the X axis and Price on the Y axis. Right now I don't really care about making it pretty just getting the lines to show up correctly. I am plotting the points and grouping by Subdivision/Builder.
So for example Subdivision A has builders Y and Z. I want to show different colors and lines for Subdivision A builder Y verses Subdivision A Builder Z.
The problem is that the lines are not connecting when a point for another subdivision builder combination breaks up that line.
The grey line and points below are not all connected as the yellow point is between the grey points so the grey line is not connected to all grey points.
How can I make the points of the same color (same Subdivision/Builder) connected via a line?
As I found out the hard way recently, this problem is often caused by null values in the data not being properly handled by SSRS. Without seeing your data, I can't be certain that's the cause, but nulls were the culprit I encountered the same behavior.
The solutions usually involve assigning values to the color of the EmptyPoint property on the Series, sometimes in conjunction with setting the EmptyPointValue to specify null handling. I've found many references to this problem on the web, but I'll only post links to the best two, both of which are on StackExchange:
The thread SSRS Line Chart NULL VALUE - Horizontal Line contains a thorough discussion of this issue. The usual workaround given is to hard-code a color expression for each line using an IIf, but sometimes this isn't an option, especially if the field you're grouping on has dynamic, unpredictable values, as my dataset did.
The picture posted there depicts clear examples of the same type of line breaks. The user named trubs posted a code sample which illustrates how to set the EmptyPoint, in case where an Iif will work:
=iif(isNothing(Fields!SelectedValue.Value),'No Color',"LightBlue")
The first reply in SSRS Line Chart Not Connecting Data Points details a workaround for cases when the EmptyPoint value & nulls are the root cause and simple hard-coded IIfs won't do the trick. Although I have yet to get my line colors to match the point markers the way I'd like, I can verify that this solution at least gives you your lines back and allows you to assign a variety of colors to them. It's fairly simple and involves merely pasting in some VB code for a couple color properties.
I was asked in the comments section to provide the details of the solutions, but don't want to plagiarize, so I'll simply do a long direct quote of JohnBob's answer:
Firstly, in order to get the lines to join up, you need to set the
EmptyPoint colour for the series.
Select your series in your chart In the properties tab (not the
dialog) drill down into the EmptyPoint property and set the colour to
be Black
This will get them joining up - yay! But part of the line is colour
and the other part is black, right? That's a bit silly, especially
considering if you leave the colour to Automatic on the EmptyPoint
that it will be transparent.
So, then we need to get the series and the EmptyPoint's colours in
sync. Using code from here. I added some code to the code of the
report.
1). Right click on an empty space on the report and select "Report
Properties" 2). In the code tab, paste the following:
Private colorPalette As String() = {"#418CF0", "#FCB441", "#E0400A", "#05642E", "#1A3B69", "#BFBFBF", "#E0400A", "#FCB441", "DarkBlue", "Tomato", "Orange", "CornflowerBlue", "Gold", "Red", "Green", "LightBlue", "Lime", "Maroon", "LightSteelBlue", "Tan", "Silver"}
Private count As Integer = 0
Private mapping As New System.Collections.Hashtable()
Public Function GetColor(ByVal groupingValue As String) As String
If mapping.ContainsKey(groupingValue) Then
Return mapping(groupingValue)
End If
Dim c As String = colorPalette(count Mod colorPalette.Length)
count = count + 1
mapping.Add(groupingValue, c)
Return c
End Function
Then we need to call this code when setting the colour of the series
and of the EmptyPoint.
Select your series
In the properties tab paste something the following (replace WhateverTheGroupIsForYourSeries with your series group name):
=Code.GetColor(Fields!*WhateverTheGroupIsForYourSeries*.Value)
Drill down to the color element of the EmptyPoint Series property
Paste the same text as from point two [e.g. =Code.GetColor(Fields!*WhateverTheGroupIsForYourSeries*.Value)]
And voila! You're done! I can't believe how unnecessarily difficult
this is :D
I hope this helps.
Just put your Fields!(YourSeriesGroup).Value in Series Groups to above of
Fields!(YourCategoryGroup).Value in Category Groups, your series group should be in both Series Groups and Category Groups (should be above of your initial category group).
And after that right click horizontal axis and select Horizontal Axis Properties. Set Axis Type to Scalar and click OK.
I am having this problem, where I have several cars, numbers and letters, and need to put 5 cars in the starting places. -random order is ok.
I' having trouble finding in AS3 a way so that the EndX and EndY of each object can be in the starting lines and be considered right no matter the order!
I'm having trouble putting the code here so, heres a titanpad with the code:
this is the code:
being (um, dois, tres, quatro) the movieclip instance name for each numbered car.

First of all, you could probably benefit by using the distance between two points formula and seeing if the distance is less than a certain value rather than checking in all 4 directions manually:
Math.abs(Math.sqrt((x2-x1)^2 + (y2-y1)^2))
Let the position of the car be (x1,y1) and the start position (x2,y2).
This formula will give you the distance between the two points in any direction, and you could test maybe whether this value is less than your offset.
As for the cars in any order part, I'm interpreting that you have your cars and you want the user to drag them to one of 5 spots, a bit like this:
spot1
spot2
spot3
spot4
spot5
All with respective coordinates. My suggestion would be to have a boolean flag for whether each spot is occupied that stops the program checking whether a car is put there after it has been taken once.
Once all these flags are true, then you can proceed.
Hope this helps.
I have plots of 3-axis accelerometer time-series data (t,x,y,z) in separate subplots I'd like to zoom together. That is, when I use the "Zoom to Rectangle" tool on one plot, when I release the mouse all 3 plots zoom together.
Previously, I simply plotted all 3 axes on a single plot using different colors. But this is useful only with small amounts of data: I have over 2 million data points, so the last axis plotted obscures the other two. Hence the need for separate subplots.
I know I can capture matplotlib/pyplot mouse events (http://matplotlib.sourceforge.net/users/event_handling.html), and I know I can catch other events (http://matplotlib.sourceforge.net/api/backend_bases_api.html#matplotlib.backend_bases.ResizeEvent), but I don't know how to tell what zoom has been requested on any one subplot, and how to replicate it on the other two subplots.
I suspect I have the all the pieces, and need only that one last precious clue...

The easiest way to do this is by using the sharex and/or sharey keywords when creating the axes:
from matplotlib import pyplot as plt
ax1 = plt.subplot(2,1,1)
ax1.plot(...)
ax2 = plt.subplot(2,1,2, sharex=ax1)
ax2.plot(...)
You can also do this with plt.subplots, if that's your style.
fig, ax = plt.subplots(3, 1, sharex=True, sharey=True)
Interactively this works on separate axes
for ax in fig.axes:
ax.set_xlim(0, 50)
fig.draw()
