 Good morning everyone, so let's go to the biostatistic session, so let's see how to make a bar graph first way, in the previous session we had seen how to make a pie chart, today we have seen about bar graphs. So I told you that by chart the criteria should be percentage, the variable should be percentage in percentage manner, but if it is not a percentage wise, it is just to value like main and standard duration of the same age group of the same gender, we can go for a bar graph. So let's start with the bar graph, so the basic three steps of the step one is just to select this, just like our pie diagram, go to insert, adjust our second step, select which one we want, we can go for this 3D or 3D, cylinder cone pyramid, so I will select cylinder one, this is our step three, done. So bar chart is ready, so bar chart always will be there is a gap with the categories, histogram it will be continuous without any gap, so now let's modify this graph, so we can put the legend by count, so this is right click, right click and format legend, so we will keep it button open, now we have to click on this bar, again right click, add data level, the values will come up, again add data levels, so now let's add a title, so go to the layout, now a chart title, it will be a whole chart, so this is weight of the participants, now you can add color, go to home, this is an area color, this is phone color, suppose you want to color this area, you can put this, and if you want to color this phone differently, then click this, so color this, now in bar graph and pie chart there is a different, pie chart there is no x and y axis, but whereas in bar graphs there will be x and y axis, so we need to add x and y axis, so again we go to layout, so we have axis titles here, so we have to select the primary horizontal axis and title below the axis, so where you can put age groups, so you can age group, again go to the axis titles and go to correct, so let's take the rotated title, it will come like this 90 degree rotation, and you have to click on that, and you have to write percentage of participants, so in all the x and y axis I will be, so this is all we do in bar graph, now we have many options we can employ, this is where we want to design, we can add this, so it will come like this, or this way, this way, we can put the values here, we can just keep that in the title, we can follow this one, we can keep on exploring it, this, basically this input is just like pie chart, then yes we additionally add x and y axis here, we go back to the last one, we add title, so let's see another example, so yesterday we are seeing the gender, the gender thing, the weight mean and standard equation, what happens is sometimes it comes like this, mean and standard equation, actually it is supposed to be here male and female in the x axis instead of mean and standard equation, so what we will do is, we go to switch column, row column, I want it, so I have to go to the switch column, take that, so it will come like this, male and female, so we just continue our routine, for math legend right click, the bottom, add data level, right click, male and data level, enter the layout, put chart at the gender, again go to design layout, access title, design the axis, something on the line axis, again in the line axis, the dotted one, it goes forward on the option, this is a grid line, and get vertical grid line, this is grid line, it is under vertical, I know grid line so it comes like this, so this is a grid line, and so if you put this show data table, the values will be shown here, show data table, legend case, again it will come like this, legend case, legend again, theorems, gender, vision, height, all these options are here, design, layout, chart, all the axis, same axis, okay so, it's all about how to make a large chart, all the bar crafts, all these options are here.
