Passing ChartControl to a function

[swcooke]

I am using the following OnRender block with a function:

public void test(index)
{
  Print(chartControl.GetXByBarIndex(ChartBars, index));
}



protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
   base.OnRender(chartControl, chartScale);
   for (int idx = ChartBars.FromIndex; idx <= ChartBars.ToIndex; idx++)
   {
     test(idx);
   }
}

I am getting the error:
The name 'chartScale' does not exist in the current context. How do I pass chartControl and chartScale into my function when the function is written above the OnRender block like this?

Hello swcooke,

Thank you for the post.

The specific error you are seeing I can't seem to see where that relates to this syntax that was provided. The error is basically saying that the variable named chartScale cant be found where you used it.

In this case, if you are wanting to pass the objects to a method, you would need to form your method correctly similar to OnRender or:

public void test(ChartControl chartControl, ChartScale chartScale, int index)
{
  Print(chartControl.GetXByBarIndex(ChartBars, index));
}

The Type is needed before the variable name in the parameters of a method: ChartControl chartControl or int index.

Then to call your method, it would be like:

test(chartControl, chartScale, idx);

I look forward to being of further assistance.
