Paste this code in excel VBE Chart(Sheet) object.

Code works fine. I was wondering if we can avoid deletion and addition of lines with every mouse move. I tried adding lines on chart activate event and then allign those lines using module level variables. But the too procedures cannot work together as by the time chart activate is triggered mouse move already takes place.

Following is thefor reference YouTube video. Please note that page margins are set to zero

I am trying to create a Chart - Crosshair cursor in excel chart sheet. Chart - Crosshair cursor lines are two lines (one horizontal and other vertical) moving along with the cursor/pointer/mousemove on the chart. Most of the stock market online charts have such interactive tool. for referenceI have referred to many webpages such as YouTube videoCalculating datapoint position with chart mouseover event

Everyone concerned faced the same problem as I did - Calulation of exact cursor position coordinates as the chart is measured in points and cursor position (windows item) is measured in pixels. Somehow, I could calculate it with formula. (Very Close)

for reference YouTube video. Please note that page margins are set to zero

I understood cursor position coordinates are determined by following factors.

  1. Windows Zoom set by "Make everything bigger" option in control panel/ settings. In Excel this can be determined using (ActiveWindow.Width)
  2. Page Size of the Chartsheet (ActiveChart.PageSetup.PaperSize)
  3. Page Orientation of the Chartsheet(ActiveChart.PageSetup.Orientation )
  4. Zoom percent of the chartsheet (ActiveWindow.Zoom)
  5. Chart area size (ChartArea.Width and ChartArea.Height)

Following is the code
