How to add marker to a chart.

In a cell, there is a chart minimized to display data for two serries. Please see the attached image. They display data for 13 months.

The current month value stored in a named-range (CurrMthCol).

Is it possible to have a red line to show the location of the current month. The value of the current month will change and it is expected the location of the marker to shift as well per the value in CurrMthCol.

Thank you.

Can you upload a sample file?

Here the sample file:

For the chart, see Sheet1!J4
For its data. see: Lookup!L3:L26

CurrMth value, see Lookup!B10

Thank you,

Mike

But, I am not able to attach it (it is not EE rather the place I work is blocking it). I wander it you could use these sample files to create a sampe chart instead.
3.45	3.71	3.8	3.4	3.48	3.7	3.42	3.58	3.39	3	3.67	3.71	3.51

Open in new window


it goes from 1 to 13

Hi  Saqib,

This marker doesn't have to be somting internal to the chart. It could be a vertical line on the Sheet1 where the chart is also located.

Then, if we could read the left position of the data area inside the chart as well as the current width of the chart, then we can interpolate and find where the marker line has to be to position the line there.

Please see the attached image.

Here is one way by adding a new series and making it a column chart and reducing the width to 0

Hi  Saqib,

WOW, this is amazing. Thank you for the wonderful solution.

Question: Upon selecting a value from Current Month: dropbox, how do you enter 10 for in the new series?

I cannot find any event to see the related VBA.

No VBA. It is an excel formula. See L2 on formula sheet.

Yes, somehow value 10 has been entered into the selected month cell and the rest are reduced to zero. But how?

I need to transfer this good solution into my worksheet where, actually, there are 5 such a graphs each already with two series like (here showing few columns for illustration):

Series1: 3.45	3.71	  3.8	  3.4	  3.48 ....
Series2: 2        1       2       3        1    ....
Series3: 0        10      0       0        0   ....       <-- marker series

Open in new window


Here 10 has been entered by the drop box into Feb column. But how?

I will simply add Series3 to all data sources so that the marker line will show in all of the charts.

But I need to learn how to reset series3 to zero except to the selected month which becomes 10.

Thank you,

Mike
