RS2008 - pie chart
I have 'outside' labels with lines pointing to the segment (although strangely this only appears to work in pdf output)
However (see pic below) the label is appearing outside the scope of the chart area
How can I force it to remain inside? (MinimumRelativePieSize is set to 70)
(pic below missing due to not being able to find an image host that isn't blocked by corp firewall)
Picture a pie chart of 25 slices, with radial lines that project through the sides.
The line from each slice then becomes horizontal, before disappearing outside.
(above actually fits tune of "Lucy in the Sky with Diamonds")
I set MinimumRelativePieSize to 50 and it seems to work ok.
I guess they need to implement a MaximumRelativePieSize property.

In the attached Google charts Pie chart the labels fit well inside the segments. Determining the length of a bit of text in HTML5 canvas is easy enough - but how do you determine whether the label will fit into a particular segment (using trigonometry) ? As you can see on the image, two of the segments don't have labels inside the segment.
EDIT: Here's an example of what I have at the moment: https://www.rgraph.net/tests/canvas.pie/in-pie-labels.html
As you see the labels for the small segments overlap. What I'm after is a way to calculate whether there's enough space for the labels at the point where they're going to be rendered. If not, I can just not draw the label like in the example image above.
Could chord size be useful to do this?
Here's the forumulae for the chord size that I found via Google:
"Chord length using trigonometry = 2 × r × sin(θ/2); where 'r' is the radius of the circle and 'θ' is the angle subtended at the center by the chord."
I sorted it (in about one hour) after 3 days of trying to calculate it with trig by using the built-in context.isPointInPath() function...
Draw the text (transparent color) to get the coordinates (x/y/w/h) of it. You might be able to get away with measuring it to get the width and height.
Draw the segment in a transparent color and do not stroke or fill it. Also, do not close the path.
Test each corner of the text rectangle (formed the x/y/w/h that you got above) using the context.isPointInPath() function. If the function returns true for each corner of the rectangle formed by the coordinates of the text, then the text will fit into the segment.
I'm making in interactive map of Russia. I need to select its regions on the picture for I can work with them. But it works incorrectly. When I try to select first region it's okay. But then I try to select another adjacent region just making new levers to existing contours. After I close the path, I want this region to become the full second area in the picture. But when I try to highlight this area, it turns out that Inkscape doesn't count this as an area. It believes that this is just a new open line. It turns out that a new area has not formed.In the picture you can see that the boundaries of the area are not highlighted everywhere, therefore the area remains open (it is not an area at all, it is a piece of a broken line)
You're using the wrong kind of object for your work. What you need is indeed a set of closed paths, but what you have is the borders only.
The easiest way to convert one into the other is to:
make sure all the separate borders touch at their ends
select all the separate borders
Path > Combine them into a single path
put a large rectangle below this combined path that covers the full area below
select both
Path > Division
Now you should have the lines cut through the rectangle.
Remove the parts you do not need, and close any gaps that are left.
I have 4 charts created in SSRS 2017 and I need them to be the same size.
Are there any settings (and where? in SSRS) to make size all the same for all of my 4 charts?
When I go into Chart Area properties, there is nothing about the chart size...
Please help!
Update:
When I clicking on the Chart Area slightly outside the actual chart I see the following Chart Properties:
You can control the position of the chart area and the plot position of the pie within the area by setting the CustomPosition and CustomInnerPlotPosition properties. Select the chart area first to see these properties.
Please note: You must select the CHART AREA object in the designer not the chart Just click slightly outside the pie to select the correct area then you will see these properties.
You can do the same for the legend too if required so you can get full control over the final rendered size.
It does take a bit of trial and error to get a layout that suits all your needs but it can be done.
You cant directly influence the size of the chart, like Hannover Fist said it depends on multiple conditions (for example the legend). What you can do is to put the legend on top or on bottom of the chart (the reason for the different sizes of your charts it that the legend text from right to left is different, thus it uses the space from the visual). This way the size of the chart should be more or less the same size. Right click on your legend Legend properties > General > Legend position. With the MaxAutoSize property from the legend you can a little bit control the size of your legend.
To your second question. No, a chart (also tablix and matrix) can only have one Dataset as source. You can see this in the chart properties at the drop down list. You just can chose one element. But you can create one big dataset with all the data for the different charts. Then assign this dataset to one chart and copy it. And then you set different filters to the charts.
For me the above didn't help. The varying sizes of pie charts related to the fact that some had been set to have their series value > label > position = outside and others were position = auto. All pie charts had their labels hidden so you coudln't see them at all but SSRS was allowing space for them when set to position = outside. This made it extremely frustrating to chase down where the difference in size was coming from. Hope this may help someone who comes across a similar issue.
Following up on my question from yesterday:
SciChart - showing labels for all ticks
Thanks to the answer I was able to get the label density where I needed it. But I still have problems with label placement. As you can see in the screenshot, rotating the labels caused them to stick upwards into the graph. I need them below the axis. I've tried everything I could find in the API that I thought might help me:
a TranslateTransform - I tried moving both X and Y both ways. No
result.
VerticalAnchorPoint and HorizontalAnchorPoint - setting
VerticalAnchorPoint to Center actually moved the labels, but only by
3mm and in the wrong direction.
Horizontal/Vertical
Alignment/ContentAlignment - didn't do anything.
I've even tried
bloating the labels by appending a lot of spaces to the strings. A desperate attempt, I know.
Furthermore, the horizontal position of the labels is not correct either. In the screenshot you can see the first bump on the graph goes down on what looks like CF.02. But in reality it's set to CF.01. It would seem the labels are moved to the left of their corresponding tick. I need them to be displayed below the center of their respective tick, like the original solution.
[edit: image removed to prevent potential client IP issues]
In the SciChart's WPF Xaml Styling a Chart example there is a demonstration of how to rotate labels by changing the AxisBase.TickLabelStyle.
This uses RenderTransform to rotate labels by 15 degrees. However, if you use 90 degrees, the labels overlap the surface.
Changing the RenderTransform to LayoutTransform forces labels to be drawn in the correct place (below the axis).
You can read more about the difference between RenderTransform and LayoutTransform here.
Are there any Settings to avoid having overlapping labels in a Pie Chart in SSRS?
I have several Charts with the same Problem, if the Slices are too small the Text will overlap. Here is a Picture of my Problem and a possible way as how i want it to be:
EDIT
edited the 3D Options so the Labels fit in like I wanted them to be. But another Problem occurred when setting rotation and inclination to zero, the colors aren't as intensive as they where before:
You can try this..
1)On the design surface, right-click outside the pie chart but inside the chart borders and select Chart Area Properties.The Chart Area Properties dialog box appears.
2)On the 3D Options tab, select Enable 3D.
3)If you want the chart to have more room for labels but still appear two-dimensional, set the Rotation and Inclination properties to 0.
to solve this:
go to the Chart Area Properties,
the Chart Area Properties dialog box appears.
expand Area3DStlye
For Shading Property select: "Simple"
This is most likely caused by an emulation of a diffuse lighting effect. The following code worked in the former dundas chart for area charts:
Chart1.ChartAreas("Default").Area3DStyle.Light = LightStyle.None;
should be something similar for the pies.
[Note: The first 3 parts of this is the same text as answered by Swathi, but there was a follow-up comment question that was not known that I discovered the answer to concerning the colors looking muted after making it 3-D. I would add a comment but I don't have enough karma now.]
1)On the design surface, right-click outside the pie chart but inside the chart borders and select Chart Area Properties.The Chart Area Properties dialog box appears.
2)On the 3D Options tab, select Enable 3D.
3)If you want the chart to have more room for labels but still appear two-dimensional, set the Rotation and Inclination properties to 0.
4) If you want the colors to not be muted when using 3-D to simulate 2-D, under Appearance/Area3DStyle change the Shading to None.
