Best Answer

time = readmatrix('Book1.xlsx', 'Range', 'A2:A202');
dp = readmatrix('Book1.xlsx', 'Range', 'C1:J1');
logDp = readmatrix('Book1.xlsx', 'Range', 'C2:J202');
ax = axes();
contourf(time, dp, logDp.')
colormap(jet)
xlabel('Time');
ylabel('Dp');
ax.ColorScale = 'log';
cb = colorbar(gca, 'Location', 'south');
ax.Position(2) = ax.Position(2) + 0.2; % move axis up
ax.Position(4) = ax.Position(4) - 0.2; % decrease the height
cb.Position(2) = cb.Position(2) - 0.18; % move the colorbar down

MATLAB: Resize and define the position of the colorbar

Your position argument is relative to the entire figure, not the plot. Adjust it to be what you want it to be.

Also, including target axes might help.

scene = imread('peppers.png');
im = imread("cameraman.tif");
ax3 = subplot(2,3,2);
ibg2 = imagesc(scene);
axis off
hold on
iim2 = imagesc(ax3,im,'XData',[16 466],'YData',[104 484]); 
hold off
iim2.AlphaData = 0.75*ones(size(im));
iim2.AlphaData(isnan(im)) = 0; 
colormap parula
caxis([0 3])
cb = colorbar(ax3); 
cb.Position = [.45 .6 .05 .1];

MATLAB: Excel Chart with 2 X-axis through matlab

I have found the solution with

Excel.ActiveChart.ChartType = 65; 
can not make 2 X-axis . I did that on ChartType = 73 and worked very well
Here the list of chart type

http://it.toolbox.com/wiki/index.php/EXCEL_Chart_Type_Enumeration

hier ist mein end Code

Excel = actxserver('excel.application'); 
% Get Workbook object 
WB = Excel.Workbooks.Open(outname); 
% Get neu Worksheets object 
WS = WB.Worksheets; 
WS.Add([], WS.Item(WS.Count)); 
Sheet=WB.Worksheets.Item('Ergebnis'); 
Charts = WB.Charts; 
Chart = invoke(Charts,'Add'); 
invoke(Excel.ActiveChart.SeriesCollection,'NewSeries'); 
Excel.ActiveChart.SeriesCollection(1).Name = 'Temperatur der Erdr'; 
Excel.ActiveChart.SeriesCollection(1).XValues=Sheet.Range(strcat('B3:B',num2str(C)));
Excel.ActiveChart.SeriesCollection(1).Values =Sheet.Range(strcat('A3:A',num2str(C))); 
invoke(Excel.ActiveChart.SeriesCollection,'NewSeries'); 
Excel.ActiveChart.SeriesCollection(2).Name = 'Temperatur der CO2'; 
Excel.ActiveChart.SeriesCollection(2).XValues=Sheet.Range(strcat('C3:C',num2str(C)));
Excel.ActiveChart.SeriesCollection(2).Values=Sheet.Range(strcat('A3:A',num2str(C))); 
invoke(Excel.ActiveChart.SeriesCollection,'NewSeries'); 
Excel.ActiveChart.SeriesCollection(3).Name = 'Temperatur der Wand'; 
Excel.ActiveChart.SeriesCollection(3).XValues=Sheet.Range(strcat('I3:I',num2str(C)));
Excel.ActiveChart.SeriesCollection(3).Values=Sheet.Range(strcat('A3:A',num2str(C))); 
% Setting the Chart Sheet Title & Chart Title. 
Excel.ActiveChart.HasTitle = 1; 
Excel.ActiveChart.ChartTitle.Characters.Text = 'Temperatur'; 
Excel.ActiveChart.Name = 'Temperatur'; 
% Setting the (X-Axis) and (Y-Axis) titles. 
ChartAxes = invoke(Chart,'Axes',1); 
set(ChartAxes,'HasTitle',1); 
set(ChartAxes.AxisTitle,'Caption','Temperatur /°C'); 
ChartAxes = invoke(Chart,'Axes',2); 
set(ChartAxes,'HasTitle',2); 
set(ChartAxes.AxisTitle,'Caption','Tiefe /m'); 
Excel.ActiveChart.ChartType = 73; 
temp=[handles.T,handles.T_E,handles.Twz]; 
%     Setting the (X-Axis) Scale 
Excel.ActiveChart.Axes(1).Select; 
Excel.ActiveChart.Axes(1).MinimumScale = min(temp(:)); 
Excel.ActiveChart.Axes(1).MaximumScale = max(temp(:)); 
%     Setting the (Y-Axis) Scale 
Excel.ActiveChart.Axes(2).Select; 
Excel.ActiveChart.Axes(2).MinimumScale = 0;             
Excel.ActiveChart.Axes(2).MaximumScale = max(handles.tiefe(:,C)); 
Excel.ActiveChart.Axes(2).ReversePlotOrder = true; 
WB.Save(); 
WB.Close;
