New FX Draw Feature

We have uploaded FX Draw 7.001.16 for both Windows and Mac. This version includes two neat new features that will allow you to modify the font of multiple objects in one command.

1. Change The Font Of All Selected Objects

This command allows you to change the font (and optionally, the font size) of every selected object. This allows you to change every font in one operation.

Many FX Draw objects have text and their own font settings. If you want to change the font of a few objects at once, this can become tedious.

The new alternative is to select all objects and choose Change Fonts For Selected Objects from the Edit menu.

You can change the font and, optionally, the font size. Note that setting the font size is not always appropriate as would affect things like the titles of graphs.

2. Change All Default Fonts

This is a very similar command (available in the Tools menu) which changes the default font for all objects. This will only affect objects created after the change but allows you to standardise on one particular font in all contexts.

New Feature – Option syncing.

We have just uploaded new versions of all Efofex products. There have been a number of small improvements and bug fixes, particularly for FX Draw and FX Stat, but the main feature that has been added to all products is option syncing.

If you regularly use more than one computer to create your work, option syncing will make your life much easier. If you change the default text size for marked points (for example), that new option is automatically saved to the cloud and will be loaded into your other computer the next time you start FX Draw. Option syncing means that you can work across a consistent environment on all devices.

Syncing works between the Windows and Mac versions of the products (for those of you forced into using a platform you do not prefer at school) but differences between installed fonts can cause some issues. If, for example, you set a default font of Helvetica on your Mac, but your Windows machine does not have that font installed, Windows will replace the font with something as close as possible.

Other than that, it should work seamlessly!

New FX Equation Video

If you have ever found yourself reaching for a calculator as you type up equations, the FX Equation calculator tool is for you. It allows you to create worked solutions quickly and easily.

If you are using FX Equation to show how to use the quadratic function (for example) you might already have typed in something like this…

(5.2+sr(5.2^2-4*3.23*1.23))/(2*3.23)

which FX Equation will turn into a fully formatted equation for you. If you actually want to evaluate this, you would probably reach for a scientific calculator and retype everything – which is both boring and slow.

In FX Equation, you can just select this string and push the calculator button. FX Equation will automatically evaluate your selection and you can paste the result directly into your next line.

We have uploaded a video of the process. You can find the video here.

The Overviews section lets you take a quick look at the capabilities of each of our six products and what they are designed to do. Take a look at these videos first.

The new, Using The Output section provides six new videos which show you how to include output from our products in your documents and presentations. They provide clear, concise instructions in the many ways our products can be used on both Windows and Mac machines.

Using the Output Videos

Finally, the How-To section provides specific instructions on how to use various features of the products. We expect this section to expand rapidly over the next few months.

Take a look at the new videos (Efofex Videos) to make sure that you are using our products in the most productive way possible.

Connectivity Issues Resolved

If you have been having connectivity issues with the new cloud versions, it is worth downloading the latest versions and trying again.

Technically speaking, we found a fault with how our products were handling proxy servers which would prevent connectivity in some cases. This issue has now been resolved and our products should always honour the system proxy settings. This should rectify a large proportion of the connectivity problems that have been occurring in some schools.

Non-technically speaking, try again – we have probably fixed the problem. Even if you have worked around the connectivity issues affecting registration (using a manual registration block), the new versions are still worthwhile as they will allow our products to back up your graphics to the cloud, making them available in other contexts and on other computers.

Microsoft Word Equation Issue Resolved


Hopefully you have not been one of those affected by the bug in a version of Microsoft Word but if you have been, there is some good news. Microsoft has now released a patch which customers have reported fully fixes the issue.

Discrete or Continuous? A Subtle Problem with Ogives.

We sometimes receive reports that FX Stat is “doing something wrong”. Often the problems are actually a symptom of a deeper issue – when is data discrete and when is it continuous?

Sometimes data is CLEARLY discrete in nature. Those cases are simple and we will not look at them.

Sometimes data is CLEARLY continuous and needs to be graphed appropriately. Again, this is easy.

Sometimes things are not so clear. For example here is some data that is not clearly discrete or continuous. Unfortunately, it is almostĀ identicalĀ to the first data set! Certainly the histogram will be the same.

Is this data discrete? Should we graph it using a dot plot? Or is it “sort” of continuous so a histogram is fine?

Often the answer to these questions depends on the context of the data, but our products (obviously) have problems with context. On the whole, we do not get involved. If you decide to graph it as a dot plot or a histogram, our products will do as they are told.

The real problem comes with ogives. If you are thinking of this data as “discrete”, the ogive should look like this (we have put in the histogram so you can see what we mean.)

Many of you are probably saying “but that is wrong – it should look like the first graph”.

Well … it depends.

If you are intending the data to be discrete, then this ogive makes perfect sense – by the time you get to 16 (as opposed to 16.5), your cumulative frequency is 8. If you are thinking of this data as continuous then you need the first graph.

Unfortunately, we cannot tell what you are thinking or, sometimes more importantly, which school system you are teaching in. Different school systems have different “standards”.

We have taken the decision to make our products treat the data as entered. If you enter discrete values with a frequency we will always draw the second, offset ogive. If you really mean your data to be continuous and want to draw the ogive, you will need to enter your data as groups.
