Grpahical selection of points on Excel charts
This will help you get started on your difficult problem. On my web site
I post a couple of techniques for getting information about a plotted point. Knowing which point it is can allow you to find out its X and Y values, and you can figure out from the series formula where the X and Y ranges are. http://peltiertech.com/Excel/Charts/...html#PointInfo - Jon ------- Jon Peltier, Microsoft Excel MVP Peltier Technical Services Tutorials and Custom Solutions http://PeltierTech.com/ _______ HowTo wrote: I have a scatter plot in one of my excel workbooks, based on data in one of it's sheets. I would like to be able to "select" a set of points on the scatter chart (maybe by drawing a box around them). I would then like to automatically select the corresponding series/values in the spreadsheet containing the data for the scatter plot. How can I accomplish this? |

Grpahical selection of points on Excel charts
I don't know if it's any easier, but I once had to enable a client to
select a region on a chart and zoom in to this region. I basically did it by having a rectangle drawn, then figuring the coordinates of this rectangle w.r.t. the chart axes, and rescaling the axes accordingly. You could do something similar, then step through the data, finding points which fall within the rectangle. - Jon ------- Jon Peltier, Microsoft Excel MVP Peltier Technical Services Tutorials and Custom Solutions http://PeltierTech.com/ _______ HowTo wrote: Thanks for your response Jon. I was able to do what you have explained below but I need to be able to select a bunch of points at once. Maybe my only option is to write an activex control which draws a selection rectangle on the area and then looks for all points that intersect with it. I was wondering if there was an easier option.
