Excel Charts - Surface Chart

Surface charts are useful when you want to find the optimum combinations between two sets of data. As in a topographic map, the colors and patterns indicate the areas that are in the same range of values.

To create a Surface chart, ensure that both the categories and the data series are numeric values.

Step 1 − Arrange the data in columns or rows on the worksheet.

Step 2 − Select the data.

Step 3 − On the INSERT tab, in the Charts group, cpck the Stock, Surface or Radar Chart icon on the Ribbon.

You will see the different types of available Surface charts.

A Surface chart has the following sub-types −

3-D Surface

Wireframe 3-D Surface

Contour

Wireframe Contour

Step 4 − Point your mouse on each of the icons. A preview of that chart type will be shown on the worksheet.

Step 5 − Double-cpck the chart type that suits your data.

In this chapter, you will understand when each of the Surface chart types is useful.

3-D Surface

3-D Surface chart shows a 3-D view of the data, which can be imagined as a rubber sheet stretched over a 3-D Column chart. It is typically used to show relationships between large amounts of data that may otherwise be difficult to see.

Color bands in a Surface chart −

Do not represent the data series

Indicate the difference between the values

You can use a 3-D Surface chart −

When the categories and the series are both numeric values.

To show the trends in values across two dimensions in a continuous curve.

Wireframe 3-D Surface

A Wireframe 3-D Surface chart is a 3-D Surface chart shown without color on the surface. This chart shows only the pnes. A Wireframe 3-D Surface chart is not easy to read, but it can plot large data sets much faster than a 3-D Surface chart.

You can use a Wireframe 3-D Surface chart −

To show the trends in values across two dimensions in a continuous curve.

When the categories and the series are both numeric values.

When the data curves behind itself.

Contour

Contour charts are Surface charts viewed from above, similar to the 2-D topographic maps.

In a Contour chart,

The color bands represent specific ranges of the values.

The pnes connect the interpolated points of equal value.

Use Contour chart −

To show the 2-D top view of a 3-D surface chart.

To represent the ranges of the values using color.

When both the categories and the series are numeric.

Wireframe Contour

Wireframe Contour charts are also Surface charts viewed from above. A Wireframe chart shows only the pnes without the color bands on the surface. Wireframe Contour charts are not easy to read. You can use a 3-D Surface chart instead.

Use Wireframe Contour chart

To show the 2-D top view of a 3-D Surface chart only with pnes.

Both the categories and the series are numeric.

Consider using a Contour chart instead, because the colors add detail to this chart type.
