GetYByValue()

Definition

Returns the chart’s y-pixel coordinate on the chart determined by a series value represented on the chart scale.

Method Return Value

An int value representing a y pixel coordinate on the chart scale.

Syntax

\<chartscale\>.GetYByValue(double val)

Method Parameters

Examples

1
protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
2
{
3
   // gets the pixel coordinate of the price value passed to the method
4
   int     yByValue = chartScale.GetYByValue(Bars.GetClose(Bars.Count - 1));
5
6
   Print("yByValue: " + yByValue); // 207
7
}

In the image below, we pass the last bar close as the value (example logic avoids using a bars ago index, see also OnRender() note #5), which in return tells us the last price displayed on the chart is at a y location of 207 pixels.
