Hello,I just can't find out whether it's possible to plot the x-axis 'below' the graph? Normally speaking the x-axis is plotted at y=0, but I want my x-axis to be plotted for example at y=-5 or y=-10. Can that be done?Greetings,Frank

Good day,

I have plotted a family of lines in one graph, and now I want to shade an area between two horizontal (parallel) lines, for example 2 and 5.
So what I did was to use the command 'filled'. First I shaded the area in vertical direction from 0 to 2 white. After that I filled the area in vertical direction from 0 to 5 for example blue.
This results in a shaded area between 2 and 5 in the color blue, what I like to have.

Question: Is there a way (a command) to fill an area between two horizontal lines more easily? So that I shade it between 2 and 5 in just one commandline. Now I first make a part white, and then the next 'layer' behind is in the color I'd like to have.

Another thing is that when I shade an area in the color white, my gridlines disappear! Is there a way to avoid this?

I have found information about shading area between two intersecting lines (can be done relatively easy), but between two horizontal (parallel) lines I still can't find a simpler way to do it.

Somebody got a suggestion?

Greetings,
Frank

 

Hello,

I've made multiple graphs, and plotted them with the command 'display'. I also put a legend to every plot I made.

But now the legend which is showed by using 'display' is given randomly. So I put in different heights from say 200 mm to 1000 mm, with 100 mm spaces in between. The legend gives me randomly all the heights: like 200, 400, 100, 300, 700...etc. Is there a way to organise or order the legend? So that I can say I want the legend to start at 200 mm and end it at 1000 mm. So a kind of an ascending height legend. That is way more pleasant to the reader, obviously.

Greetings.

Hello, Is there a way to assign mutiple variables at once using the 'if-then' statement?For example: if A:=3, then B:=434 and C:=52 and H:=2039So that I fill in these variables B, C and H one time and then when A is chosen to be a value, all other values are assigned automatically. Like filling in a table actually.In a simple 'if-then' statement I assign one variable, which works well.a:=10if a:=10 then b:=4elif a:=20 then b:=3end if:b ends up being 4I don't know how to add variable C and H, without getting an error.It should be very simple in my opinion, but I just don't see it.Greetings,Frank
Hello,When I plot graphs I can simply add colors, gridlines, labels, etc., but when I want to do this with the command 'Explore' it doesn't work.The commad 'Explore' sees the words 'color', 'labeldirections' and other commands as extra variables.For exmaple is does recognize 'labels' and 'title', which I can fill in, but it doesn't some of the other commands I would like to insert.I have a formula for deriving the eigenfrequency of a concrete beam, where I want to add some things to (like the things mentioned above).Somebody knows what the difference is between 'normal' plotting and plotting with 'Explore'?Explore_-_Adding_Col.mwGreetingsFrank
