The concept:

The long term aim of the project is to develop a fully functional software, known as DataViz, for

plotting and processing datasets, which will be eventually deployed and released for all students in

the department to use in their reports, data processing, and as a show case of an authentic

experience of software development for the students of ELEC$362.$ The development is planned over

$5$ years, which started in $2022.$ Each year the cohort of ELEC$362$ will be asked to make a major

upgrade to the software $($will be referred to as the control version in this report$).$

Each header file of every class in the control version $($source files$)$ of the project contains a comment

explaining what the purpose of the class is$.$ The features currently available in the app can be found

under "Help" menu.

Upgrades required for this year:

For this year you are asked to implement the following upgrades to DataViz $0\mathrm{.}0($the control version$)$

to end up with DataViz $0\mathrm{.}2$:

Introduce a way in the app allowing the user to change the width of the curve, its colour, and

its style$*.$

Update the design of the help window so that it becomes organised into sections which are

easy to add to and expand in the future.

Introduce a way in the app where the names of loaded Datasets can be made available to the

user, so that they can add a comment to describe what each dataset represents.

Define another mean in the app to enable the user to draw a dataset.

Introduce a way in the app where it allows multiple datasets to be plotted into a single

graph window $*.$

Create an entry "Function" under the menu "Analysis", which should allow the user to input

a mathematical expression containing the names of datasets. For example, $"$D$1*$exp$(-$D$2)".$

For this purpose, use the classes defined in the header atmsp.h $($An example test project

showing how to use this header file has been uploaded to CANVAS$)*.$

Adding a feature for a histogram plot $($you can generate the histogram in GSL and plot it in

QCustomPlot via QCPBars class$).$

You may assume that all the datasets in the app will have the same $x-$coordinates. To refer to what

asterisks mean please refer to the last question in FAQ section.

After you are done with the upgrade; make sure that:

All the features you add are working well.

You updated the help window in the app to include instructions on how to use the app after

the features you added.

You handled a range of potential errors that may be experienced in the updated app.

It is an expectation from everyone to consult Qt documentation to find any functions or classes that

might be useful for the implementation of the project. Finally, you should make the programme as

Note: The mark will be based on how your application behaves on a computer in

the lab. Check your app on one of the computers in the lab to make sure it works

as you expect before submitting your work. Make sure compiling your app is

straightforward and does not need any special compilation instructions.
