Early warning - the Preview Chart goes red

If the Preview Chart is on, its border will turn red if you make a mistake. Display the chart (PF5) to see the message.

The chart is not there at all - your data is wrong. You'll get a message like this:
```
              ADM0540 E PIE CHART CANNOT BE DRAWN IN AVAILABLE CHART AREA
```
You have asked for an impossible chart, too many pie charts on a screen or a Venn diagram where the overlap is bigger than the population. Read the message or messages to see if they help. If not, look in this book: either under the message in Appendix B, ICU messages or under "Traps" for the chart type involved.
Messages but chart (more or less) OK - probably not enough room. You'll get a message like this:
```
              ADM0514 W LABEL(S) OMITTED ON X AXIS
```
The ICU cannot draw one of the details of your chart. Most likely there is not enough room. Look carefully at the message. If the problem is labels, the best answer is to shorten them, see "Words on your chart" in topic 1.6.7. Look for mis-typings in axis or data values.
Bypass: Pressing PF6 removes the messages.
A funny looking chart but no messages.
This is probably the hardest problem. Check that your data values and axis lengths are correct. Check that you are not using logarithmic axes (panel 4.3), check for indexing in panel 2.5 and axis orientation in panel 5.2. Look in this book at the "Traps" section for the chart you are drawing.
