Charge order (CO) is established in most known hole underdoped cuprates and considered as universal property on equal footing with the pseudogap phase and superconductivity. In La-based cuprates, several studies on the charge and spin order have recently lead to controversial results in the overdoped regime. To address open questions on the origin of CO, its connection to the tentative pseudogap critical point and the spin order, we performed a thorough resonant inelastic x-ray scattering study in La2-xSrxCuO4 and La1.8-xEu0.2SrxCuO4 with dopings up to x=0.25. The results provide a comprehensive overview of the CO in La-based cuprates and elucidate the doping evolution of the incommensurability, correlation length and temperature dependence.
