Generate your graphs
Every hour our weather data is uploaded to a MySQL database on the web server. You can query this database and graph the data using this form.

1) Select the parameters to plot:

Parameter 1
Parameter 2

<< Plot both parameter 1 and parameter 2

Make the fill colour of parameter 1 have a transparency of and parameter 2 have a transparency of (x100%)

If the checkbox is checked, then both parameters will be plotted on the same (line) graph for the same date range specified below. If not checked then only parameter 1 will be plotted.

By default the parameters will be plotted with the same scale. This is useful for comparing like parameters (i.e. Outdoor Temperature and windchill). However, for comparing un-like parameters, for example Barometric pressure and windspeed a second auto-scaled Y scale should be created for the second paramter. If the checkbox below is checked, a second scale will be created for parameter 2 and displayed on the right hand side of the plot.

<< Create a second scale for parameter 2?


2) Select the time range to plot

Quick shortcuts:

Today's data since midnight
This Week
This Month

This Year


OR select range to plot:


Date Range (select below)
Date Range at same time of day (select below)

Plot range to at (ONLY if checked above)

Hint: Selecting the same date for start and end will plot the data for that one day.


OR compare different data on the chart. This will generate two plots of parameter 1on the same graph, one for each date range. In this case selecting parameter 2 above is ignored, and all options relating to parameter 2 relate to the second plot.

Date Range (select below)
Date Range at same time of day (select below)

Plot1 range to

Plot2 range to at (ONLY if checked above)

** Only works with Line Plot**


3) Select the plot type

Select a plot of this type

4) Select the Lineplot options (Note: Barplot does not support all options)
