Composite Chart (2D Line) and scrolling

Thomas posted over 16 years ago

I have a composite chart that I want to be able to scroll the X axis. I have set the following:

ultraChart1.Axis.X.ScrollScale.Visible = true;

ultraChart1.Axis.X.ScrollScale.Scale = 0.2;

ultraChart1.Axis.X.ScrollScale.Scroll = 0;

but that does not seem to work. The composite chart contains a single 2D Line chart (for now).

In the composite charts there are custom axis. You have to find the right one. This should be something like:

ScrollScaleAppearance scaleAppearance = this.ultraChart1.CompositeChart.ChartAreas[0].Axes[0].ScrollScale;
scaleAppearance.Visible = true;
scaleAppearance.Scale = 0.2;

ScrollScale property for now is not public visible, because it's not tested well, but you can try to use this.

That worked. I also found I can add the information when I am setting up the axis so I don't have to guess which index it is.
AxisItem axisX = new AxisItem();
axisX.OrientationType = AxisNumber.X_Axis;
axisX.DataType = AxisDataType.String;
axisX.SetLabelAxisType = SetLabelAxisType.ContinuousData;
axisX.Labels.ItemFormatString = "<ITEM_LABEL>";
axisX.Labels.Orientation = TextOrientation.VerticalLeftFacing;
axisX.ScrollScale.Visible = true;
axisX.ScrollScale.Scale = 0.2;

Thanks for your help.
