New Data Selection & Plotting | Website Update

Data Selection & Plotting | Website Update

This is just a small update to the data viewing tool on https://photosynq.org, but we think, it will be very helpful for your data analysis.

Data Selection

Plots

With switching the plotting library to Plotly we introduced selecting a series by using the lasso tool or box selection tool to generate a new series, instead of using the filters (Goodbye Flot, Hello Plotly | Other Website Updates). Now you can also use the inverse of a selection as a new series or generate both at the same time. Just check the appropriate box in the dialog before you create a new series or download selection.

The new selection dialog allows you to not only select a range of markers as a new series, but also the inverse of your selection or even both as new series.

Map

Now you can also generate a new series by drawing a rectangle or a polygon around markers on the map. When viewing graphs you can use the selection tools to create new series of data selected, or the inverse.

Select a group of markers by dragging a rectangle or polygon to create a new series (buttons in the center top). Similar to the plot, the map as well allows you to use the selection, the inverse selection or both as new series.

Dashboard

A new panel is available, which lists all the Data Quality Issues, which were found in your project, listing each issue with a count of affected measurements. You can now generate a series containing these measurements for an easier screening and potential flagging.

Plotting

What’s in my selection?

When you are working with a scatter plot and you are using a color gradient as a third dimension, it might be hard to tell, if for example, a certain crop variety is enriched in your selection. Now you can use the Enrichment feature to plot fractions of a category for each series.

Just select the bar-graph tab, check Enrichment and choose a category. The bar-graph will display the fractions as to the following selections:

  • category / series Will show the fraction of category appearances in each series compared to the total appearances in each series.
  • category / total Will show the fraction of category appearances in each series compared to the total appearances.

2D Heat-Map

The 2D Heat-Map will now adjust based on the selected series and not only show the map for all all series combined.


Spreadsheet

If you save photos along with your measurements, no matter if it is a project question or if you take them as notes, inside the spreadsheet you see a small image icon. When you hover over the icon, you will see the picture instead on top of your list of series. The same is true for long arrays of numbers. Instead of those, you now see a chart icon and hovering over it, will bring up a line graph.

Copying the data still works the same. You will get all the data or the link to the picture.

The “ID” and “Series” columns are now sticky and will stay visible when scrolling vertically in the table.

Statistics: Chi Square Test

We added another statistical test, the Chi Square test. This allows you to compare categorical data.

Dashboard

The functionality of the dashboard got extended a little bit. The graphs you save to the dashboard are now images, so you can simply save them to you hard-drive.

Hiding Advanced Parameters

As I am sure you’ve noticed by now, we at PhotosynQ like to provide you with a lot of data. Not just the primary parameters (e.g. Phi2, PhiNPQ, Light Intensity (PAR), time, etc) that you are interested in, but also many other parameters that may go into calculating those parameters. However, viewing all of this data in the plotting tool or spreadsheet view may be a bit much for some users.

We have now added a feature that allows users to decide whether or not they want to view the primary parameters and Project questions together with the Advanced parameters (e.g. absorbance_420, FvP_over_FmP, etc) or if they would prefer to hide the advanced parameters. The new default setting is to hide the advance parameters. If you want to view these parameters, select the settings icon near the Add Series and click the Show Advanced Parameters checkbox. Now all of the parameters output by the MultispeQ will be available in the Plot Data, Spreadsheet, Map and Statistics tabs.
