New Training Videos – Now With Tables Of Contents

We have uploaded new versions of our training videos for FX Draw and our Equation, Function Graphing and Statistical Graphing tools. The new videos replace our old email tutorials and show you how to use all of the latest features.

One new feature of the training videos is the table of contents that we have added to the videos.

This allows you to quickly find the topics you are interested in.

The new videos can be found on our Information & Training Videos page.

FX Stat/FX Draw – New Graph Type – Normal and Normal Cumulative Curves

In the July 5 2019 versions of FX Draw and FX Stat, we have added the ability to add a normal distribution curve and a cumulative normal distribution curve for a data set.

Two new graph types

The new graph types draw an idealized normal/normal cumulative curve for a selected dataset using the dataset’s calculated mean and standard deviation. They allow you to demonstrate how closely your data fits a normal distribution.

The cumulative normal distribution curve can be combined with the calculated cumulative frequency curve (as well as a cumulative histogram) to clearly demonstrate differences.

As part of this upgrade we have also added some smoothing to our cumulative frequency curves – particularly when produce from grouped data.

Download the latest FXDrawTools pack to access the new features.

FX Chem – Precipitation & Gas Evolution Arrows

We recently received a request to allow FX Chem to create gas evolution arrows (↑) and precipitation arrows (↓). We have added this capability by using the \ character for precipitation (think of it as sliding downhill) and the / character for gas evolution.

Examples Using The New Arrows

The new feature is available in versions of FX Chem produced after June 26 2019

New Title Bar & Trial Mode

The latest versions of our products have added your registered name and current license status to the title bar.

Registered Name & Expiry Date

This allows you to keep an eye on the current status of your license and will also make it clear when you have not logged into your account.

No Account Details Entered

The other significant change we have made is to our trial mode. Previously, we have offered full access to the software for thirty days, after which the software expired and allowed no access. Unfortunately, this often meant that teachers would install the software and not log it in – because it appeared to be working correctly. Thirty days later, the trial period would expire and we would receive a support request to help them get their software working.

Our new products never “expire”. They make it clear that you have not logged in AND overlay all graphics with a watermark. This lets you still fully evaluate the software while preventing the 30-day expiry issue.

NEW Equation Contexts

In the May 2019 versions of FX Equation and FX Draw, we have introduced Equation Contexts. These are quick buttons that you can use to set up FX Equation for different contexts that you are writing in.

The five available contexts are shown below.

Most of the time you should use the General Algebra context but if, for example, you are creating some Vectors, switch to the Vector context and FX Equation will set itself up to make creating vectors as simple as possible.

Contexts make it easier to set up some fairly obscure options that FX Equation has always had in order to produce exactly what you are after.

NEW Quickly Change Graph Colors

You have always been able to change the colors of functions and statistics graphs – but it has always been a bit slow and fiddly. Each function or data set needed to be changed individually which was slow and error prone.

In the latest versions (19.05.27), we have added the ability to quickly change ALL of the functions or data sets.

Function Graphs

The quick entry screen for functions has seen two changes. Firstly, any changes made to line widths or point sizes now affect ALL functions. You can, for example, set all function lines to 2pt with one change.

The second change is the addition of a palette button. Pressing this allows you to change the color settings of all function lines. You have the choice of setting all functions to one color (normally black) or to choose one of twelve different color schemes, including the “classic” color palettes. Once you have chosen a color palette, pressing Set As Default will keep your current settings for all future graphs.

If you wish to change the color or line width of an individual line, you now need to change to the Function Properties tab.

Statistics Graphs

We have also added color schemes to statistics graphs.

The colors of individual data sets can be changed by pressing the data set buttons.

Issues With The OneNote App for Windows 10

Microsoft has been promoting its OneNote (Microsoft store) app to users and preferentially installs it for Office 365 users on Windows machines. Unfortunately it has quite a few issues, and not just for Efofex Software. The main impact it is having on our users is that you cannot directly paste Efofex graphics into the OneNote app. We are aware of the problem and have approached Microsoft to help resolve it. Please note that we believe that the root-cause of the issue is the OneNote App as the graphics can be pasted into OneNote 2016, OneNote Online, Word – in fact everywhere apart from the OneNote App.

Two Versions of OneNote in Windows

The new App version of OneNote is not very popular. If you go to the website and search for “Hate OneNote” you will find hundreds of people bemoaning the cessation of development of the desktop version (OneNote 2016). We believe that Microsoft has made a strategic error with the new version and is quite likely to make a change in the future. Either way we will be working to try to mitigate the effects of this version.

Many schools do not permit teachers to use the new app as all notebooks MUST be stored in the cloud. OneNote 2016 allows local notebooks which are mandated by many schools. If you are one of these lucky teachers, well done!

If You Are Being Affected

The best solution is to download and install OneNote 2016. This is free and is
(arguably) a better version. You can find it on this Microsoft page. Most teachers should use the 32 bit version of OneNote 2016.

If the OneNote app is mandated in your school there are two options:

  1. Use OneNote Online when inserting graphics into a notebook.
  2. Paste the graphics into Word FIRST and then copy them (from Word) to the clipboard to be pasted into the OneNote app.

Rest assured that we will continue to work on the issue.
