Bar charts are used to visualize one or more variables over a specified time period. To create a new bar chart select the variables that will be displayed on the graph. Be sure to select variables with the same units of measure.
Tip: Select variables with similar magnitudes as the axis will automatically scale to the values.
Once the component variables are selected, enter a title, timeframe, and frequency. The timeframe dropdown menu has several commonly used time periods for quick configuration. Custom timeframes, including those smaller than the current hour, can be set by selecting the "Custom" option.
The frequency setting defines the size of the intervals on the horizontal axis - in the case of a bar chart, this corresponds to the width of each bar. The frequency selection ranges from one minute to yearly intervals, representing the time between each displayed data point. Certain frequencies are restricted to smaller timeframes. If a high-frequency option (e.g., one minute or five minutes) is not available, select a shorter timeframe to prevent the chart from becoming too dense to read.
