MATLAB - 添加校准滑块到图形
MATLAB - adding calibrated slider to figure
我正在尝试向该图添加校准滑块。
它是一个带有 3d 冲浪图的图形框架。
现在如您所见，我设法使用“uicontrol”命令创建了一个滑块，但我无法对其进行校准，也无法在其上创建任何刻度。
我尝试使用“uislider”，它创建了一个漂亮的滑块，就像我想要的那样，但出于某种原因，我无法在图中添加其中一个（但是只有当我使用 uifigure 创建原始图形时才有效）当我这样做时，我无法在其中绘制我的冲浪图，我也不知道为什么）。
这是我的代码。
主脚本。
clear vars
filename = ('C:\Users\Ali\Desktop\Documents\DataVis\Projekt\data\day\filenames.txt');
%This line simply gives us a table of all filenames in this file.
T = readtable(filename);
tsize = size(T);
tsize2 = size(T, 1);
%initialize figure.
mainFigure = figure('name','CylinderHeatMap','NumberTitle','off','Color',[.3 .3 .3]);
%extracts the content of the table as a categorical array.
% {rownumber,variablenumber}. {100,1} = row 100, variable 1.
%converts the categorical array into a string array.
%joins the string array across the column.
%string(T{100:105,1}); implies from row 100 to row 105 and use variable 1.
%This line simply adds the name of the file at row 100 to the path of the
%file. Hnece we get a full filepath.
filename = strcat('\Users\Ali\Desktop\Documents\DataVis\Projekt\data\day\', string(T{100,1}));
map100 = getCylinderHeatMap(filename);
roterOven = createSurfCylinder(map100);
s = uicontrol('Style','Slider','Parent',mainFigure,...
'Units','normalized','Position',[0 0 1 .025],...
'Value',1,'Callback',{@slider_callback1}, 'min', 1, 'max', 1000);
脚本 getCylinderHeatMap 并不重要，因为它只是 returns 一个包含用于创建圆柱体的值的矩阵。
圆柱体创建脚本。
function cylinder = createSurfCylinder(matrix)
%Load heat map.
load('myHeatMap.mat','myHeatMap');
%%
%Cylinder creation
Sample_Range = 255 - 0;
Temperature_Range = 450 - 50;
Multiplier = Temperature_Range/Sample_Range;
map100 = matrix.*Multiplier + 50;
%Setting up the figure%
Radius = 1.5;
Number_Of_Data_Points = 360;
theta = linspace(0,2*pi,Number_Of_Data_Points);
%The xy values according to radius and number of points%
Z_Circle = Radius*cos(theta);
Y_Circle = Radius*sin(theta);
map100 = rot90(map100);
Height = 512;
Z_Circle = repmat(Z_Circle,Height,1);
Y_Circle = repmat(Y_Circle,Height,1);
X_Length = (1:512)';
X_Length = repmat(X_Length,1,Number_Of_Data_Points);
figure('Position', [10 10 800 500])
clf;
close;
%surf(X_Circle,Y_Circle,Z_Height,'Cdata',map100); vertical
%subplot(1,3,1:2);
cyl = surf(X_Length,Y_Circle,Z_Circle,'Cdata',map100);
title("3D Heatmap Plot");
zlabel("Z-Position");
ylabel("Y-Position");
xlabel("Length(Cm)");
%Reverse Y axis.
set(gca,'Ydir','reverse')
colormap(myHeatMap);
colorbar;
shading interp
Maximum_Value = 450;
Minimum_Value = 50;
caxis([Minimum_Value Maximum_Value]);
%Show the image in the subplot and add custome color coding to it.
% subplot(1,3,3); imshow(rot90(map100));
% colormap(myHeatMap);
% caxis([Minimum_Value Maximum_Value]);
cylinder = cyl;

请提供任何帮助，因为我已经坚持了 2 天了。
MATLAB GUI uislider() 带捕捉点
使用回调函数绘制的随机测试数据，下图是滑块值变化时绘制的。可以在这段代码中的回调函数 Snap_Slider() 中获取滑块值，图中的绘图和图像可以随意更新。除了滑块之外，我建议添加 uieditfield 以获得更精确的 image/plot 选择。可以在任何预期由用户或其他代码修改的元素上调用回调函数。可以根据需要调用回调函数。在这种情况下，它是在值更改时由附加到元素的 .ValueChangedFcn 事件指示的，在这种情况下，uislider 名为 Slider。可以按以下形式创建回调：
Slider.ValueChangedFcn = @(Slider,event) Callback_Function();
回调函数中的输入也是可以接受的，可以包含其他 UI（用户界面）元素。
Components/Elements包括：
图→uifigure()(父容器)
情节 → uiaxes()
图片 → uiimage()
滑块标签 → uilabel()
滑块 → uislider()
