NCharts is intended to be a quick-look display of a wide variety of data, not a tool for detailed analysis. The plot options will be limited to keep things simple and usable across a variety of display sizes. NCharts uses the Highcharts.com javascript plotting library which has some nice features for zooming and displaying point values.

Introduction

To plot a set of variables over a period of time:
  1. Choose a Start Time or the Track Real Time option
  2. Select a Time Zone
  3. Select a time Length with units
  4. Select one or more Variables, which may be organized under tab panels by variable type, site name, or alphabetically
  5. If provided, select one or more Stations
  6. Hit Plot
When the plot is ready the screen will scroll down to display the plot.

Time Series

ISFS Sites and Stations

For ISFS projects, to identify the locations of measurements, a site suffix is typically appended to the variable name, such as "T.2m.abc" to indicate that the measurement was from site "abc". In order to provide a manageable way to select variables, NCharts will group the variables from each site under a separate tab.

For ISFS projects where a measurement is repeated at more than one site, variables are stored in NetCDF form with a "station" dimension, and will not have a site suffix. For example: "T.2m". These variables will be provided under a "stations" tab, and checkboxes are provided for selecting one or more stations. The variable names will be shown on the plot with their station name.

Height vs Time Data

If a time series variable has a additional dimension, such as height or bin number, a color-coded heatmap time series will be plotted, with an associated color key. With a mouse, hover over the plot to display the point values. On phones, tap a trace to highlight it, then tap again to display the point values.
