Horizontal barplot x value base point - bar-chart

Who is the fastest, smartest R user out there??? Easy fix for pros!
I am creating a horizontal barplot and displaying results from traits as a percentile. The industry I work in has the 100th percentile as the lowest and zero the highest. So that is no problem plotting that as you can see with my current command: barplot(mydata$Percentile, names.arg=mydata$Trait,horiz=T,las=1,xlim=c(100,0),base=50)
abline(v=50, lty=2)
Current version
Currently I have the 100th percentile on left and zero on right. The bars on the plot however come from the right hand side of the plot.
PROBLEM: I would like them to start from 50. For what I am looking to do please see the picture attached from a MATLAB example where they have set the base value at 25. MATLAB example

One possibility to solve this is to subtract 50 from your values and plot this without axis.than you adapted your axis:
values <- c(100, 10, 55, 30, 120)
barplot(values-50, horiz=T, axes=F)
axis(side=1, labels=seq(0,120,20), at=seq(0,120,20)-50, xpd=T)
ps: I guess your first lines, the opening, prevent a lot of people to answer.

Is it possible to limit the device/camera movement in Facebook AR Studio?

For example there is an image using canvas with a rectangle in World Space. In doing so the camera/device can look around freely with the image placed into the "real" world. I wonder if there is a way to limit that "movement", spanning left to right, top to bottom but the device/camera view is limited at a certain point. Even if users turn the device/camera 360degrees, the view is stuck at a certain point. Say if the user pans left the camera/device stops at rotationY: 9, If right then stops at rotationY :-15, rotationX is stuck at 0.
I saw there's a BoundBox in the documentation but not sure what that is. There's a DeviceMotionModule but no idea how to use it. I don't know what the script example given is suppose to do.
Look into using DeviceMotion. https://sparkar.com/ar-studio/learn/documentation/reference/classes/devicemotionmodule
The script example rotates the 3d plane according to the rotation of the phone.
You will have to do some maths to position your objects according to rules and signal you get from DeviceMotion.
Using the reactive module you can access the "Clamp" method which is actually made to restrict values between two bounds. I recently found this out because I had a similar problem. From this page
clamp(x: ScalarSignal, min: ScalarSignal, max: ScalarSignal): ScalarSignal
Returns a signal with the value that is the value of the given x signal constrained to lie between the values of the given min and max signals.
Note: The behavior is undefined if min is greater than max.

SSRS : Overlapping Line in Line Chart

I have created a line chart which has the date as X-axis and Y-axis as calculated median value and its grouped according to "FileName". Problem is that some of the "FileName" has same median values which makes line overlap thus not able to see all the lines. Attached image shows only 5 lines but there are total 10 lines. After running query I found out other 5 has 50 as the median which makes it overlap with one of the line.
I tried using transparency and secondary axis but wasn't able to achieve the desired result. Is there any other solution to try out ? Thanks!
This is more of a data presentation issue than something specific to SSRS. If you are stuck on using a line chart, then I've only used two options:
1) Increment lines to different widths. For example, in a chart with 3 lines, the width is set to 5,3,1 pts.
2) Change the values insignificantly to offset the lines. Obviously this depends on the data being visualized as shifting the line slight (multiply by 0.1) may be allowable or highly discouraged depending on your situation.
Trying to do either option with 10 lines (and up to 5+ stacking) is not going to be very good.
I think Viking is right and you might want to check out other visualization options. Grouped column charts perhaps or just split your chart into multiple charts on the page (i.e. four separate trend charts)

SSRS - Major/minor gridlines spacing

I have an SSRS report with a bar chart with multiple series by CountryName Category group. What I want to do is have gridlines which split each country like below:
However in SSRS the major gridlines seem to interval with the line in the middle of the country name when the grid interval is set to 1 like below:
Can someone point me in the right direction into how to rectify this?
Also is there a way of adding the X axis in SSRS to start from zero like I have in my first graph?
Thanks
You can do it, there is an offset property on the grid lines (horizontal and vertical are separate). Click one one of the gridlines and look in the properties pane. Change the offset to 0.5.
Gives you this.
I'm not sure what you meant about starting from zero on the X-Axis, you have negative values so you'll start from a negative number. If you meant you wantde zero aligned to the middle. You can do that to. You need to set the min and max values of the horizontal axis to the following
Min Value:
=MAX(ABS(Fields!MyValueField.Value), "MyDataSet")*-1
Max Value will be:
=MAX(ABS(Fields!MyValueField.Value), "MyDataSet")
Basically we take the ABSolute largest value and use that as the extent (*-1 for the min value). The problem is that zero might not show so you'll have to play around with the Axis properties maybe to get that working. I'm sure it's possible but I don't have time to test at the moment.
My test data is not great as the number are large

Large ratio values ssrs chart

I have a bar chart that show the count of number of models for each agency,
The problem is that I have a large difference between the values that makes the report to look not so good.
Does anyone have any ideas of a good way to resolve this problem?
Have you considered using a logarithmic scale?
With your chart Right-click the y-axis, and click Vertical Axis Properties.
In Axis Options, select Use logarithmic scale.
Leave the Log base text box as 10 (this is the scale most commonly used by logarithmic charts)
This will display a chart with a scale that goes up by a factor of 10 for each ‘unit’ up, so the distance between 1 and 10 is the same as that between 100 and 1000.
For example the shown dataset is displayed as this chart when using the logarithmic scale
This method is a simple and recognised way to clearly show values of widely different scales.
Update
If want an indicative bar for the vales that are 1 then you could use the expression
=iif(Fields!val.Value = 1, Fields!val.Value * 1.1, Fields!val.Value)
To make all values that are 1 equal to 1.1 so showing a tiny bar appearing a the bottom of the chart, as seen here
Unfortunately I don't know of a way to change that first 1 to a zero (formatting-wise). This is partly because you are now using a logarithmic scale and zero and negative values don't really exist. This is due to a fundamental property of logarithms in mathematics, that
LOG10(10)= 1
LOG10(1) = 0
LOG10(.1)=-1
Therefore, when you perform a log10 of zero, it just doesn't exist.

Chart issues with SSRS

I am having a problem with getting a stacked area chart to display the right data in SSRS 2005.
On my Y axis, I want a scale from 50% to 100%.
On my X axis I have a set of dates formatted in a style that was necessary for the report (so varchar).
My data consists of 3 data fields which are decimal numbers and contained between 0 and 1, each with a specific date.
My problem is the scale of the Y-axis. I have set the maximum value to 100, the minimum to 50, the interval to 5, and the format to "p" for percentages.
On the preview in the layout tab, this all appears fine (Y-axis starting at 50% up to 100%).
However whenever I generate an actual report it goes from 5000% to 10000% for some reason. I have no idea how this is happening and it completely ruins the report.
I have tried tinkering in the properties for several hours but to no avail.
If this has happened to anyone and they have found a solution, or if anyone has any suggestions I would be very grateful.
Thanks.
When you use percentages, everything factors by 100.
If you want to format and display a value as 50% , it needs to be 0.5 unformatted. Percentages are therefore values between 0 and 1.
Excel and pretty much every other tool works that way.
If your values are all stored as percentages already, then you might just want to append the % symbol at the end of your values. Or better, divide everything by 100.
50 per cent means just that anyway; it means 50 per hundred (cent means 100) so 50/100 is another way of writing 50%.
