In the iOS version, the creation of charts is locked. (To unlock the command, see Welcome.)
There are two ways to insert a chart into a document:
▪Inserting charts via PlanMaker
| The most convenient way: Create or open a chart in the spreadsheet application PlanMaker and copy it to the clipboard. Then switch to TextMaker and paste it there. |
Alternatively, you can simply create a new empty chart using the ribbon command Insert | Chart frame  in TextMaker. You then enter the numeric values to be displayed in a dialog box, which you can open with the Edit data button. |
