Use plot() instead of stem().

The black curve in your original post doesn't look smooth to me. But anyway, you can smooth the data and then plot the smoothed data with a sliding polynomial fit filter, sgolayfilt() in the Signal Processing Toolbox.
polynomialOrder = 2; % Larger for less smoothing.
windowWidth = 7; % Larger for more smoothing.
smoothedSignal = sgolayfilt(signal, polynomialOrder, windowWidth);
plot(smoothedSignal, 'b-', 'LineWidth', 3);
grid on;
title('Smoothed Signal', 'FontSize', 20);
If you don't have sgolayfilt(), try movmean().
