 Welcome back to my classes. So today we will be continuing our graph scenario. So now we are seeing about the line graphs. So we have already covered the pie graphs and bar graphs. Now we have into the line diagrams. So usually pie graphs will be done for percentage comparison and the other comparison will be done by if two categories and the values and two or three categories the values will be compared using bar charts. But if same group is being followed up at regular intervals or if there is a clinical trial before and after in such scenarios we can use the line diagram. It will give the overall picture of that scenario or that experiment. So usually line graphs will be used for clinical trials and follow-up studies. So here we can see a scenario three people and their exams in three internal and final exam marks. So Mr. A, B, C their first, second, third internal and final exam marks are given. So let's start our three-step tutorial. So the first step is to select this. The second step is to go to the insert button and select the line diagram and our last step is select any line graph you can select. So usually I use this one that ordered line graphs. So it gives the follow-up of these three people for a period of time. That is this is how they performed for first internal, second internal, third internal and for final exam we can compare it. So as you should do right click format legend. So format legend we put the legends at bottom and we can give some title for this. Go to layout, chart title, above chart, exam, performance. So values over this and just do the click just the time on this. So the values will be visible. So similar way all the three values you can do for all the participants is exactly click on each color. Any interval you can click all values will be appeared. Okay. Now it is little bit congested. So you can just widen this graph grid line techniques can add some grid lines here. Horizontal and minor vertical grid lines you can put some minor grid lines. All things by exploring each one which you can click on next flow and do it slow. So next you can add the access titles. Pickle access you keep rotated. It is total marks in x axis you can keep exams. So if you want you can put some color look good. Some light color. Now it's fine. Now what you have to do is you can have many options. Go to the design you have options here and number of options. The most commonly used is if it is very congested use this one. So the scores will be showing at bottom. A, B, C they have this marks because when we are putting marks over here it is too much congested. So in order to avoid that we can use this method. So there are many ways you can opt this one. This one will give us some lines. So this is how you make line graphs. Again you have this different colors option. So you can go for any color. So anything is fine. So we will go back to our first one. Just keep one. I am doing it. So this is how we do. Usually we cannot put standard deviation here. Usually we put only main value. So suppose we have main and standard deviation. We permanently put main value standard deviation we don't put. So this is how you make line graphs. So line graphs is basically for follow-up studies or clinical trials. So that's all about line graphs. So I will come up with new class session. Okay, thank you.
