FX Chem 3 Beta Release

Posted on April 17, 2014 by efofex

FX Chem 3

We have uploaded beta versions of FX Chem 3 for both Windows and Mac. A long time user of FX Chem 2 (and FX Chem 2 has been around a long time) recently said “I don’t know what else you could add!” Well, we have found a few things worth doing but you can rest assured that we have not changed it too much.

What’s New? Obviously, Mac compatibility was a major focus during development but we have also added the ability to change formatting for bits of an equation. This lets you highlight one reagent in red for instance.

We have also improved integration with Word for Windows making the process more seamless.

Finally, we have added a number of new output formats that let you produce equations that embed natively into Word as well as LibreOffice, Latex and even Moodle.

FX Equation

Thanks yet again to our dedicated band of beta testers, we are releasing FX Equation 5 for both Windows and Mac.

New Features

FX Equation 5 adds some nifty new features and is much more than just a Mac release.

  • We have included FX Autoquate which automatically determines which bits need to be formatted as equations.
  • We have added full text formatting to text and equations.
  • You can now strikeout sections of your equation. Ideal for showing “cancelling”.
  • We have added new symbols such as minus/plus, double-struck C, Z, Q, R and N for number sets and the empty set symbol.
  • FX Equation can now output LaTex and LibreOffice equations as well as generate native Word equations.
  • Integration with Word (Windows) is much improved and more reliable.
  • Hundreds of other improvements.

Starting a Histogram at 0

Posted on April 16, 2014 by efofex

Question:

I was hoping you could tell me how to begin a histogram at 0. When I do a histogram the first bar starts before 0. I can change the width but can’t seem to change where the histogram begins.

Answer:
The histogram tool will group your raw data as best it can but, if you do not like what it does, the best thing to do is to create your own groups. That way you can produce anything you like.

FX Stat also has the capability to group your raw data into groups that you define but that is a different process.

Perpendicular Angle Marks Not Drawing Correctly?

Posted on April 13, 2014 by efofex

Question:

Why are these perpendicular angle marks being drawn as squares? I just want two lines.

Answer:

Although it is not obvious from your diagram, this is because you are drawing shaded angle marks and the shading has been set to white. When angle marks are shaded, they draw the complete square.

Here I have marked an angle as perpendicular and shaded it. In your case the shading is white but I have made it green so that you can see it. To get a normal perpendicular mark, select the angle mark (as shown above) and change the shading to none.

When there is no shading attached to the angle mark, FX draw will only draw the two lines rather than the square.

Marking Angles

Question:

The angle marking tool is not allowing me to mark the angle I want. How can I fix this?

Answer:

I think your question is relating to this situation – where you are trying to mark angle ABC but the angle marking tool is always finding ABD or DBC.

Finding Integrals Between Two Curves

Posted on March 22, 2014 by efofex

Question:

Can you show me how to shade the area between the curves step by step?

Answer:

FX Graph/Draw can only find integrals between functions and the red curve is a relation. To get what you are after, we need to add a function that FX Graph can use. In this case, the function is y=sr x. Continue reading →

How Do I Get This Object Exactly Where I Want?

Posted on March 22, 2014 by efofex

Question:

I am trying to align this text box but it keeps jumping as I move it. I cannot place it exactly where I want.

Answer:

As you move things around, FX Draw will lock on to the background grid and objects like your text box will move in 5mm (or your default grid size) increments. This can make it difficult to align things exactly with something already on screen.

The solution is to hold down the Ctrl (control) key as you move things around. FX Draw will ignore the background grid and you can align things to pixel perfection.

Shaded Background Behind Text

Posted on March 22, 2014 by efofex

Question:

Is it possible to make an opaque background for text?

Answer:

Text/equation boxes can have shading applied. Just select the text box and change the shading using the top toolbar.

Text attached to lines cannot have a shaded background.
