hi everyone i have a problem with a line chart. normally a chart shows categories and associated values, but in this case i want to display only some categories. i mean i want on my chart every value stored in my db, but only a few categories. suppose i have 3 categories (cat1, cat2,cat3) and associated values(val1,val2val3); on my chat a want to display all the values (val1,val2,val3) but only, for example, cat2. what can i to do? regards Manuel
