x-axis as cateogies
lazarus / 55-TAChart

Hi,

I'm struggling to get a graph with categories as the x-axis and counts
as the y-axis from an access database.
I've got it setup and have managed to get data displayed in a bar
chart, but I just cannot get it to display the category names under
the x-axis.
When I select the x-axis field to be the name, it just crashes saying
that 'xxxxx' is not a floating point?

Any pointers would be great.

Thanks
Dave

Hi,

Ok so it looks as if the x-axis has to be a number, and for my
purposes it just needs to be a sequential number. So I've created a
filed in my datasource with just a sequence in it, then used the
category field as the labelfield. That works, but it would be great if
the x-axis could default to just a sequential number, unless of course
it can, but I've just missed it.

The x field must always be numeric (or empty to get a sequential
value). Get the categories names from the text field. Look at attached
demo which is a modification of the code which I posted for your other
question.

Thanks wp,

As I mentioned, I worked it out and I went back and removed the dummy
sequence field from the x-axis entry and it works fine.

Thanks again
