I have a strong reason for you to use a dynamic chart range.
It happens sometimes that you create a chart and at the time when you update it...
...you have to change its range manually.
Even when you delete some data, you have to change its range.
Maybe it looks like that changing a chart range is no big deal. But what, when you have to update data frequently?
You do need a dynamic chart range.
Are you sure, I need a Dynamic Chart Range?
Alright, let me show you something.
Below, you have a chart with month wise amount and when you add amount for Jun, chart values are same, there is no change.
Now the thing is, you have to update chart range manually to include Jun in the chart.
So what do you think, using a dynamic chart range is a time-saver?
Using Data Table for Dynamic Chart Range
If you are using 2007 version of excel or above then using a data table instead of a normal range is the best way.
All you have to do, convert your normal range into a table (use shortcut key Ctrl + T ) & then use that table to create a chart.
Now, whenever you add data to your table it will automatically update the chart as well.
In above chart, when I have added the amount for Jun, chart get updated automatically.
The only one thing that leads you to use next method is when you delete data from a table, your chart will not get updated.
Solution to this problem is when you want to remove data from chart just delete that cell by using delete option.
Using Dynamic Named Range
Using a dynamic named range for a chart is bit tricky but it’s a one-time setup.
Once you do that, it’s super easy to manage it.
So, I have split the entire process into two steps.
Creating a dynamic named range for dynamic chart
To create a dynamic named range we can use OFFSET Function.
Quick Intro To Offset: It can return a range’s reference which is a specified number of rows and columns from a cell or range of cells.
We have following data to create a named range.
In column A we have months and amount in column B.
And, we have to create dynamic named ranges for both of the columns so that when you update data your chart will update automatically.
Here are the steps.
- Go to Formulas Tab -> Defined Names -> Name Manager.
- Click on “New” to create a named range.
- Now, in the new name window, enter the following formula (I will tell you further how it work).
- Name your range “amount”.
- Click OK.
- Now, create another named range by using following formula.
- Name it “month”.
- Click Ok.
At this point, we have two named ranges, “month” & “amount”.
Now, let me tell you how it work
In above formulas, I have used count function to count the total number of cells with a value. Then I have used that count value as a height in offset to refer to a range.
In month range, we have used A2 as starting point for offset and counting the total number of cells having in column B with counta (-1 to exclude heading) which gives reference to A2:A7.
Changing source data for the chart to the dynamic named range
Now, we have to change source data to named ranges we have just created.
Oh, I am sorry I forget to tell you to create a chart, please insert a line chart.
Here are the further steps.
- Right click on your chart and select “Select Data”.
- Under legend entries, click on edit.
- In series values, change range reference with named range “amount”.
- Click OK.
- In horizontal axis, click edit.
- Enter named range “months” for the axis label.
- Click Ok.
All is done. Congratulations, now your chart has a dynamic range.
Using a dynamic chart range is a super time saver & it will save your lot of efforts.
You don’t have to change your data range again & again. Every time when you update your data your chart is instantly updated.
