How to programmatically scale ReportViewer?

SLko

Hello,

I have some questions about WinForms.ReportViewer.
1. Can I access report toolbar And if can, how
2. Is there any way to programmatically scale chart so that min and max of x- and y-axes would be different than initial
3. I have to display and hide lines in chart at runtime. Would be nice if I can display checkboxes in the legend. Anyway, is there any way to control visibility of lines at runtime

Thanks

Well...
1. I have found toolbar by: reportViewer.Controls.Find("toolStrip1", true);
2. I think it can be made by report filters only ...
3. In progress
Small question: where are experts

So, I have found answers on all my questions! Alone...
2. Use of series filters is not good idea. It cut boundary points... I have use report parameters to restrict points by using scale min & max (X Axis & Y Axis pages).
Example:
Scale minimum: =Parameters!ScaleMinValue.Value
Scale maximum: =Parameters!ScaleMaxValue.Value
3. Hiding of lines I've done by changing value.
Example:
=Iif(Filter(Parameters!Ids.Value, Fields!Id.Value).Length = 1, Avg(Fields!Value.Value), 3000)
This must be written in Edit Chart Value dialog, Value combobox.
Ids is multistring parameter that contains id to be shown

Hope this helps if you would have same tasks
