In the business community KPI graphs are often shown to represent important metrics related to performance. Here are few important tips to remember while making KPI graphs-
- Don’t have distracting backgrounds: While showing important statistics it is important to not have background which may distract the viewer from the underlying message. Bright colors should be avoided while creating graphs as they might be distracting. Use of gridlines should be done wisely as they might make the chart feel too clustered.
- Use titles and labels: Efficient use of titles and labels can help the viewer understand the chart better. With proper labeling the user can immediately understand what is being measured against a certain parameter. Chart titles give the overall description of the issue being addressed in the graph.
- Use dual axes: The use of two axes is that it allows the user to measure two values against each other with proper measures. If the two metrics have different scales it is important to show them on different axes. Showing them on the same axis can give an altogether different meaning to the graph.
- Too much data is bad: If too much information is added to the graph, it may confuse the user. The reader can get overwhelmed by the amount of information and the meaning of the graph may not get through. Hence the graphs should be separated and only relevant information needs to be shown.
- Pick the chart wisely: While deciding on the graph, the designer should be careful on the chart selection. Pie charts and donut charts must be avoided as they might not communicate the correct values of the data. They can create a wrong impression on the viewer and can be misleading. Simple bar charts and line charts should be used instead to convey information.
