This is not a game breaking bug - but I wanted to bring it to your attention.
I select "Sea Temperature".
I select "Temperature Anomaly" - it populates the sea surface temperature anomalies and highlights the "Temperature Anomaly" button. All good.
I select another parameter to show - example "Wind" - populates wind data - All good.
I then select "Sea Temperature" again - the "Temperature Anomaly" button is highlighted (I like it - keeps the last known selection), however Actual Temperature data are what is being show - NOT Temperature Anomaly data. I then have to click the "Actual Temperature" button, then click the "Temperature Anomaly" button in order to see the Temperature Anomaly data again. This also happens if I leave the page and click back on my browser in order to return to the page.
Currently on Windows 7 Professional with Service Pack 1 - using Google Chrome Version 60.0.3112.113 (Official Build) (32-bit)
I've attached a few captures of this - numbered 1-5.
Keep up the great work!!!!!!!!
