chart question only twelve value I can add in the Y axis
I have a form to collect data.
It contains many details, just like 0101, 0102, 0103..., 0201, 0202...., 1501, 1502, ....
Now I have 15 large items 01xx, 02xx,...., 15xx.
After calculating the total sum of each large item, I got the total sum of each item: 01total, 02total, ...., 15total.
Now I could like to draw a chart that Y axis is the total values, and X axis is from item 1 to item 15.
However, I can only type 12 items in the Y axis.
Is there anyone know how to solve this problem?
Or, is there another way to achieve the same result?
