What's the
limitation on creating a 3D chart? In creating the chart above, the xvalues were entered not a real numeric values but as 'category labels.' This was done in Step 2 of the Chart Wizard. Excel does not attach any numerical significance to these labels. All the labels are arranged so that they are next to each other at equal distances. Similarly, the yvalues are not real values. Excel draws a 3D chart by charting multiple series and overlaying a surface across all the series. What looks like yvalues of 98, 99, etc., are nothing but series names specified in Step 2 of the Chart Wizard. This example deliberately picked xvalues such that the difference between adjacent values was the same (1 in this case). The yvalues have the same characteristic, with each being 1 more than the previous one. Any category chart which contains equidistant xvalues will look OK. However, consider the case where the x values are 8, 9, 10, 15, and 20. The chart corresponding to this data set is shown on the right.
