Graphing multiple variables allows you to display large amounts of information for a given site within the one image. The following details one possible procedure for creating a multiple variable chart for a given time period, where the variables on the y-axis are distributed evenly over one A4 sheet. Such charts are routinely drawn for meteorological time-series data.

Create a new Chart

1. Click Chart in DataSight Ribbon to open a blank chart in the Main Panel.
2. In the Levels Panel, highlight the Level whose data you wish to display.
3. From the Variables Panel, left-click and drag the first independent variable to the y-axis.
4. Continue to drag additional independent variables to the y-axis, to plot your multiple series.

Modify the Chart Type

By default variables are added as line charts and you may wish to change the series type.

1. Right-click on the chart and select Chart Editor.
2. On the Series tab, click Change.
3. Select the different Series type from the Series Gallery and click OK.
4. The modified Series is now displayed in the Series list.

Adjust the Chart Axes

The chart may look crowded, so you will need to distribute the axes over the chart.

1. Select the Axes tab and press the + button below the list of available Axes at the left of the window. This will add a custom Axis for the additional variables. Press this button twice more, for the other additional variables. You should now have several custom axes labelled 0, 1, 2... etc.
2. To position these axes, select Left Axis in the list.
3. Select the Position
4. Leave the Start % as 0, change the End % of the axis to the proportion of the chart it is to occupy. For example if you have four variables to display, then you may wish to end the first axis at 25%.
5. Select Custom 0 axis from the list.
6. Change the Start % to where the first axis ended and change the End % accordingly. For example, where there are four variables to display, the second axis may start at 25% and end at 50%.
7. Repeat this procedure until the last axis to be positioned ends on 100%.

Label the Axes

1. Select the Axes Title
2. Following the procedure of selecting the axis from the list and making changes to the right, title each axis.

Assign Variable to Axes

1. Select the Series Section. This area is where you move the variables (as series) on to their dedicated axis.
2. Select the first variable from the drop-down list and select the General
3. From the Vertical Axis drop-down list, select the appropriate axis.
4. Repeat this procedure for the remaining variables and axes.

Separate the Axes

1. Select the Tools tab from the header bar.
2. Click the + button.
3. Select the Axis tab and Add a Colour Line.
4. The options for the newly added colour line are displayed on the right. Select Left Axis from the Axis drop-down list.
5. Press the Clone Select Custom 0 from the Axis drop-down list.
6. Press the Clone Select Custom 1 from the Axis drop-down list.

Give the chart a Title

1. Select the Chart Section from the header bar.
2. Select the Titles tab and enter an appropriate name for the Chart.
3. Close the Chart Editor.
4. Save the chart by clicking Save on the Quick Access Toolbar.
