Question

I have made bar diagram with horizontal lines, it works fine, and a combobox where the users can change to a pie chart, with sort of work, when the user change to pie chart it works fine, but when change back from the pie chart to the bar chart, only the bars come, not the title, the x-asis tick, they axis tick nor the custom labels for the y axis.

I have search the net, and tried the following lines

myPane.YAxis.Scale.IsVisible=true;
myPane.XAxis.Scale.IsVisible=true;
myPane.XAxis.Scale.Min = 0;
myPane.XAxis.Scale.Max = 30;
myPane.YAxis.Scale.Min = 0;
myPane.YAxis.Scale.Max = 9;

myPane.Legend.IsVisible = true;

but it only shows the bars there and nothing else. it works fine, if the bars diagram is made before, and without shift to the pie-chart

Answer 1

Found a solution, finally.

Making a rectangle for prooper size

RectangleF rc=new RectangleF();

rc.X=0;
rc.Y=0; 
rc.Width=zgc.Width;
rc.Height=zgc.Height;

Make a new graph rather than a new masterpane

zgc.GraphPane=new GraphPane(rc,"title","x - axis","y-axis");

Link the new pane

myPane=zgc.GraphPane;

That worked for me, now I get the corect size, and all values and ticks.
