asp.net charts: Legend overlapping with X-axis - charts

I am creating a Chart (DataVisualization.Charting.Chart) programmatically, which is a Stacked Bar chart.
I am also adding Legend entries programmatically to it. I want to show the Legend at the bottom of the chart.
But, while doing so, the Legend overlapps with the X-axis of the chart.
Here is the code I am using:
Private Function GetLegend(ByVal legendName As String, ByVal s As Single) As System.Windows.Forms.DataVisualization.Charting.Legend
Dim objLegend As System.Windows.Forms.DataVisualization.Charting.Legend = New System.Windows.Forms.DataVisualization.Charting.Legend()
objLegend.Name = legendName
objLegend.Font = New System.Drawing.Font("Verdana", s)
objLegend.IsDockedInsideChartArea = False
objLegend.Docking = Docking.Bottom
Return objLegend
End Function
Below statement adds that Legend to the chart
_msChart.Legends.Add(GetLegend("SomeValue1", 10.0F))
Any idea, what is missing? I want to show the legend at the bottom only, but it should not overlapp with the X-axis.

I had the same problem today. Try adding:
objLegend.Position.Auto = true
objLegend.DockedToChartArea = "yourChartAreaName"
That did not help me but I found on the net that this might be helpful (and clean solution).
What actually worked for me was moving chart area to make space for legend so it no longer overlaps. My legend was on top so this code worked for me:
chart.ChartAreas[0].Position.Y = 15
You can try resizing it instead, forcing it to be for example 20 pixels shorter than chart.Size.
Hope this helps.

I had an overlapping legend/chart area problem as well but none of the other suggestions here seemed to make any difference. I think the problem stems from legend text wrapping to two lines and the sizing algorithms not taking account of this.
The ideas here got me thinking more clearly about the problem though, and I was able control the size and position of the chart area using the following.
Chart1.ChartAreas[0].InnerPlotPosition = new ElementPosition(15, 5, 90, 75);
There's not much intellisense on those parameters, but as well as I could deduce, the parameters are all percentages of the total chart area (I initially thought they might be pixel values and got some very odd results). So what I've written above would set the plot area to start at 15% in from the left edge of the chart image and 5% down from the top, and have a width of 90% and a height of 75%.

Custom number format for y-axis on Chart

I have created a chart with 2 axes that acts as a panel chart (see image)
As a panel chart I only want to show the portions of the relevant y-axes to the chart next to them. For example, for the right-most y-axis I used a custom number format to exclude anything less than 0:
_(* #,##0_);_("";_(* 0??_);_(#_)
But for the left most y-axis, I'm stuck. I want to show -400 to positive 400. I've tried 2 different options, but neither is producing the desired effect.
[<0](#,##0);[>500000000]"";#,##0_)
[<0](#,##0);[<500000000]#,##0_);""
Here is the result I'm looking for:
I learned something new today (and a bit weird) regarding formats and chart axes
After some experimenting, this is what I ended up using:
[White][>500]_(#,##0_);(#,##0);0;
The odd part: When you change the Display Units of the axis (for me, millions), then the formatting no longer recognizes the original amount (500,000,000).
Once I figured that out, I was able to work out the solution.

plotyy function showing two x-axes but only want one

I am using the plotyy function to produce the chart in the image below.
I have two issues with this chart. First issue being having two x-axes I want the zero on the left hand side of my chart to be level with the zero on the right hand side. Is there anyway I can make this happen?
Lastly I want to put some labels on the x-axis however you can that I labels have numbers on top of them. I only want the labels to be visible which I cannot seem to do?
Below is my code.
x_labels = data_cell(2:end, 1);
risk_tot = cell2mat(data_cell(2:end, 2));
risk_cont = cell2mat(data_cell(2:end, 3));
[pp,h1,h2]=plotyy((1:length(risk_tot)),risk_tot,(1:length(risk_tot)),risk_cont,'bar','stem');
set(gca,'XtickL',x_labels);
set(h1,'FaceColor',my_Blue2(40,:),'EdgeColor',my_Blue2(40,:))
set(h2,'Color',my_Orange(1,:),'LineWidth',0.5,'MarkerEdgeColor',my_Orange(1,:))
set(pp(1),'Box','off')
set(pp(2),'Box','off')
Update
I have managed to resolve the second issue with the x-axis labels. I simply added the line below. This sets the second x-axis labels to empty.
Still can't fix the first issue.
set(pp(2),'XTickLabel',[]);
Try linkaxes:
linkaxes(pp,'y')
You may need to adjust the axes limits with pp(1).Ylim = ... to get the desired result.

Sigmaplot: How to scale x-axis for correctly displaying boxplots

I want to display overlapping boxplots using Sigmaplot 12. When I choose the scale for the x-axis as linear then the boxes do indeed overlap but are much too thin. See figure below. Of course they should be much wider.
When I choose the scale of the x-axis to be "category", then the boxes have the right width, but are arranged along each single x-value.
I want the position as in figure 1 and the width as in figure 2. I tried to resize the box in figure 1 but when I choose 100% in "bar width" than it still looks like Figure 1.
many thanks!
okay, I found the answer myself. In Sigmaplot, there is often the need to prepare "style"-columns, for example if you want to color your barcharts, you need a column that holds the specific color names.
For my boxplot example I needed a column that has the values for "width". These had to be quite large (2000) in order to have an effect. Why ? I have no idea. First I thought it would be because of the latitude values and that the program interprets the point as "1.000"s, but when I changed to values without decimals, it didnĀ“t get better.
Well, here is the result in color.
Have fun !

is it possible to create dojo chart without axis?

I'm using a dojo chart to display data in a bubble chart. However, I don't need the axis but if I remove the axis, it screws up the display of the data. I can fudge axis not being there by hiding labels and coloring the lines white but then there's still this large margin on the left and bottom of the chart. How do you make a dojo chart without the axis while still having the min/max set correctly?
chart1.addAxis("x",{ type : 'Invisible' /*, .... */ });
Matthew, if you are still looking to tweak the margins, the solution here:
dojox charting: remove the padding around the chart
worked for me.

how to set custom interval to horizontal axis in Flex Charts

I am trying to set custom step (interval) to my Line Chart's horizontal axis.
The chart gets its data from a grid. The grid has a lot of data and it is displayed accurately but because there are so many data points the horizontal axis is screwed up. I wanted to set a step on horizontal axis so that you get an idea when you see the graph without hovering the mouse on a data point!
thanks for any help!

heylo people!
I have solved the mystery!!!
just add a horrizontalAxisRenderers to your Chart
and set the property canDropLabels to true!
<mx:horizontalAxisRenderers>
<mx:AxisRenderer axis="{horiAxis_B}" canDropLabels="true"/>
</mx:horizontalAxisRenderers>
axis being the name of the axis
you are done!!
but if you still have questions, you can always contact me here:
