Core Plot IOS Tutorial: Learn the Easy Installation Process!

Are you in charge of inserting graphs and charts into a project for your office work? Or you might be an app developer looking for ways to make the interface more interactive? Core Plot is the tool that is designed for these tasks. You can ask how?

Well, the core plot is one of the coolest libraries that can make your applications lively. It is a 2D plotting dependency to input attractive graphs or charts into apps or official projects.

But are you thinking that it is only for pro-coders and not for common people? If yes, then this core plot ios tutorial is just for you.

Here, we will start from zero and make the installation process as easy as 1-2-3, even for beginners as well. So, if you are ready, let’s get into it.

How to Install Core Plot for IOS

There is a pre-requisite that you need to fulfill before looking into the core plot download process. You see, core plot installation comes in two parts.

If you use cocoaPods then downloading the core plot gets super easy. Any developer would know what it is. But let’s not be too sure.

CocoaPods is a dependency manager for third-party libraries. Along with the core plot, thousands of other libraries that are being used in app development are backed-up by cocoaPods. It is the most reliable source for pods out there. And here’s how you can install the cocoaPods if you haven’t already:

  • First off, you need to open the terminal.

  • Now go to the official site for cocoaPods and look for the command. Just scroll through the page and you will find it.
  • Just copy the command and paste it into your terminal. Make sure you have a good internet connection for this process to be successful.
  • The command “sudo gem” will install the tool automatically. We use this command to access Ruby in MacOS. CocoaPods are established using Ruby. So, it’s logical to use this command.
  • To check which version you have downloaded type “pod –version.” Press enter and below you will see the version mentioned clearly.

Now that we have our Pods, let’s install the core plot right away:

  • After the installation of cocoaPods is over, give the path of your project file. Type “cd” and drag the project file beside it. Then add “pod init” at the end of the path. It will initiate the project and get it ready to have a pod into it. Click enter and that’s it.

  • Check into the podfile. Podfile is a place where you have to describe accurately what kind of pod you are trying to install.
  • To describe the pod type, go inside the official page of cocoaPods. Here they will provide you with a long list of various libraries. Just pick the one you want. In this case, we will be going for the “core plot.”
  • Once you have clicked into the core plot, you will see a demo of what this Pod is all about. But we are looking to copy a command like “pod coreplot.” Just scroll a bit down and you will find it.
  • Now paste it into the podfile that we opened earlier.
  • Close the podfile window and move back to the terminal. Write the command “pod install” here to demand action.
  • Press the red icon on top to save every change you made. And press enter.
  • The installation will begin.

That was all you had to do for adding this application to your project.

Whenever we want to download, update or remove a particular dependency from the list of pod files, we run the command “pod install.” And you can find the downloaded pod in podfile.lock. It keeps track of each version of pods that you saved using cocoaPods.

Create a Bar Graph Using Core Plot

In order to draw a graph, you need to know about “CPTGraphHostingView” first. Indeed, it is the graph holder that acts as a frame. So, you need to assign it. The basic part is over. To make it more interesting, ensure to include extensions like “CPTScatterPlotDataSource” and “CPTScatterPlotDelegate.”

Now if you want the graph to be more user interactive, try adding the feature that allows them to pinch-zoom in or zoom out. This is nothing quite fancy at all.

That said, it can lead to user satisfaction as they feel more empowered. So, to add this feature to your graph, just set “allowsUserInteraction” on the plot space. And similarly, if you want to remove this, turn off the property “allowPinchScaling,” and that’s it!

Create Axis Lines with Core Plot

Axis line is the straight line at the edge of your graph. The horizontal line is X-axis and the vertical one is called Y-axis. Both the axis represent certain values and ultimately the shape of the graph. So it is very important to know how we can draw these lines without making errors.

Choose the class “CPTXYAxisSet” from CorePlot. You will automatically see X and Y axis in the graph. This class is also responsible for labeling and making ticks.

Set the Plot Space Using Core Plot

The plot is a graphical representation of the data set provided. And plot space is the area between two axes. It is an open space where you have to place dots according to the coordinates. Where you scatter the dots will eventually decide the structure of your chart or graph. You need to be very accurate while doing it.

The instance which is responsible for this feature is “CPTXYPlotSpace.” It has subclasses that handle work like converting data coordinates into an actual drawing. You can also set the range by using “CPTPlotRange.”

Frequently Asked Questions (F.A.Q’s):

What Is Core Plot?

In the fewest possible words, the core plot is a two-dimensional graph plotting dependency. It is one of the seventy-two thousand pods available within cocoaPods. Also, it creates graphs and pie charts that allow user interaction.

Can You Use Core Plot On iPhone?

The good news is that the core plot runs perfectly fine on macOS, tvOS, IOS. You can draw amazing charts with the help of it. It doesn’t come with any irritating bug issues so that’s a relief.

3. How to Install Core plot for IOS?

You need to download cocoaPods first. It is a dependency manager that contains all third-party libraries in it. After you have installed cocoaPods use the command “pod coreplot” and the “pod init” to activate it.

Conclusion

There are other alternatives for creating graphs, this includes paid tools and manual coding. But guess what? Both have huge disadvantages. Tools will require you to spend an arm and a leg, whereas we are no expert in conducting coding for hours.

So, it seems like using a core plot is the best option available. And the best part is that you don’t have to be a coder. Just clicking and copying the right texts will get your work done.

That was the end of our core plot ios tutorial. So, what are you waiting for? Make the visual representation of boring data more fun and interesting with a core plot!
