PaintInfo and CPI_PIXELTOVALUE

[User (Legacy)]

Hi All,

(ChartFX IE5.5)

I need to get the position of cursor as "value".

I write the following code. It works well for y but not for x.

I have used PaintInfo because PixelToValue can't be used in javascript but

the documentation says that CPI_PIXELTOVALUE is obsolete and there is no

documentation about it.

<SCRIPT  LANGUAGE="JavaScript" FOR="ChartFX1" EVENT="LButtonDblClk(x, y,

nSerie, nPoint, nRes)">

   var lX

   var lY

   var temp = ChartFX1.PaintInfo(5, CHART_ML(x, y))

   lX = CHART_LOWORD(temp);

   lY = CHART_HIWORD(temp);

   alert(lX + " " + lY)

</SCRIPT>

Can anyone help me please?

PaintInfo with CPI_PIXELTOVALUE can not be used from JavaScript either as

the parameters require pointers.

What exactly do you need to do with this script ? maybe we can find another

way of doing it.

When you use PaintInfo with CPI_PIXELTOVALUE we return a double with the

value of the specified pixel in the "current" axis (default is Y axis), so

your code needs to be something like

<SCRIPT  LANGUAGE="JavaScript" FOR="ChartFX1" EVENT="LButtonDblClk(x, y,

nSerie, nPoint, nRes)">

<!--

    var yValue = ChartFX1.PaintInfo(5, CHART_ML(x, y))

    ChartFX1.CurrentAxis = 2

    var xValue = ChartFX1.PaintInfo(5, CHART_ML(x, y))

    ChartFX1.CurrentAxis = 0

    alert(xValue + " , " + yValue)

-->

</SCRIPT>
