Hi,

What will be the custom formula (and its inverse formula) for scaling on X axis for the following values:
100, 125, 150, 750, 1350, 1950, 2550, 3150

Thanks
Prashant

Hello,

Thank you for sending the data and expected graph. It looks you just want to make sure all x values show as tick labels in order.

Select column A and choose Column: Set as Categorical and then highlight column B, C and D to plot column graph will do the trick.

When setting a column as categorical, it will treat the column as text and enough unique value will be mapped to a number from 1 to N. Tick labels will be categorical and read from the categorical column. You can see it from Tick Labels: Bottom subnode of Axis db.

Then you can customize your Y axis to be log10, and also double click plot to customize the fill color list on Group tab.

Thanks, Snow Li

Hello Sean

Thank you very much for your prompt response. However, I am afraid that I am still facing the issue.

Following is an example data which I wish to plot as column graph:



I wish to obtain a graph like this -



In OriginLab, if I use linear scaling in x-axes I get the following -


I tried custom formula for scaling on x-axes, as shown below -


However, I get the following plot -


Kindly advise if I am doing something wrong.

Thanks
Prashant

Hi Prashant,
If you have data set like the following:



Double click on the Y axis to bring up the dialog box and choose Custom Formula as Type under Y Axis:Scale. Input Direct Formula, Inverse Formula as shown in figure below and choose Major Ticks Type as By Dataset and select column A as input.



You will have the label like the figure below:
