Since 2017.02 FEWS supports the possibility to plot arrows markers showing direction on plots, which for example can be used to create a plot of wind speed where the arrow markers signify the wind direction. The report module also supports such markers. Configuration for these markers must be included in the TimeSeriesDisplayConfig.xml, as described in the Time Series Display Configuration Guide under the "Directional arrow markers" section. In addition, for the direction time series to be available in the report module, the direction time series must be included in the chart in addition to the speed time series. The direction time series is NOT added automatically.
Direct reference to existing display ID
A new feature in FEWS version 2021.01 is the option to create a chart using a direct reference to an existing Display ID in the DiplayGroups configuration. You can configure this using the <DisplayChart/> element like this:
<displayChart id="testDisplayChart" width="400" height="400">
<displayId>testDisplay</displayId>
</displayChart>
Using a classic <chart/> tag you have to reconfigure each chart separately for both the TimeSeriesDisplay on screen and the Report Export. The Benefit of this may be that you can optimize the way the charts look in a printed or web based report, which may have a different resolution, fonts and other features relative to the computer screen. However, if you just want the charts in the report to look the same as the do on the screen, using the existing Display ID in a <displayChart /> element can save you a lot of work.
Spatial plot snapshots
Gridded time series can be visualized in a report by means of snapshots. The snap shot is an image depicting the time series spatially.
