Date does not show in tooltip

[sheng]

I'm using financial extension. The tooltip shows the open, high, low, close value but no date is shown.

How do I add the date to the tooltip? I tried ToolTipFormat, but I can't get open, high, low, close value using Format.

Please help. Thanks

Hi sheng

 

This is an unsupported feature in Chart FX, you cannot get directly the OHLC values in order to set them in the Tooltip.  But, from spoken with a Chart FX developer, he was able to come up with a work around for you. It involves changing the Text property of every point in the chart and set the tooltip to %L right before the chart gets painted (I was only able to make it work at the PrePaint event).

 

private void chart1_PrePaint(object sender, ChartFX.WinForms.CustomPaintEventArgs e)

{

  if (string.IsNullOrEmpty(chart1.ToolTipFormat))

  {

  for (int i = 0; i < chart1.Data.Points; i++)

  {

chart1.Points.Text = DateTime.FromOADate(chart1.Data.X).ToString().Split(' ')[0] +

"\r\n" +

"Open: " + chart1.Data[0, i].ToString() +

"\r\n" +

"High: " + chart1.Data[1, i].ToString() +

"\r\n" +

"Low: " + chart1.Data[2, i].ToString() +

"\r\n" +

"Close: " + chart1.Data[3, i].ToString();

  }

 

  chart1.ToolTipFormat = "%L";

  }

}

 

I must remind you that this is a workaround over an unsupported feature.
