Grid Surface Chart

Grid surface charts are a type of data visualization that represents three-dimensional data, where data points are organized in a grid. The data points in each row and column in the grid share the same x and y values, whereas the z value is specified per data point. A variation of the grid surface allows the user to specify a color for each data point thus adding a fourth dimension to the plot. This type of chart is often used to visualize continuous functions or data sets that vary continuously across multiple dimensions, such as terrain data.

Sample Table Format

X ValueY ValueZ Value
0 0 2.2
0 1 1.8
0 2 1.4

The table contains data points represented by X and Y values indicating their respective positions on the chart. The Z value signifies the data value or elevation for each point. By utilizing this data, you can generate a Contour Surface Chart that displays contour lines indicating the value or elevation of the data at each point on the chart.

Best practices for using surface charts

Surface charts are a great way to visualize data in three dimensions, making it easier to identify patterns and relationships. Here are some best practices for using Surface charts effectively:
  • Choose the right type of data: Surface charts are ideal for visualizing data with three or more variables, such as temperature, humidity, and pressure. Make sure that the data you choose is appropriate for the chart type.
  • Use appropriate colors: Surface charts can have multiple color schemes, and choosing colors that highlight the important aspects of the data is important. Make sure to use colors that are easy to distinguish and don't cause visual strain.
  • Use appropriate lighting: Lighting can significantly impact the appearance of Surface charts. Use lighting that highlights the important aspects of the data, such as areas of high or low value that don't obscure any important details.
  • Keep the chart simple: Surface charts can be complex, so keeping them as simple as possible is important. Remove any unnecessary elements that can distract from the important aspects of the data.
  • Use appropriate labeling: Labeling ensures the viewer understands the presented data. Label the axes and provide a legend explaining the meaning of any color schemes used in the chart.
